-# Mostr Design & Internals
-
-## Nostr Reference
-
-All used nostr kinds are listed on the top of [kinds.rs](./src/kinds.rs)
-
-Mostr mainly uses the following [NIPs](https://github.com/nostr-protocol/nips):
-
-- Kind 1 for task descriptions and permanent tasks, can contain task property updates (tags, priority)
-- Issue Tracking: https://github.com/nostr-protocol/nips/blob/master/34.md
-    + Tasks have Kind 1621 (originally: git issue - currently no markdown support implemented)
-    + TBI: Kind 1622 for task comments
-    + Kind 1630-1633: Task Status (1630 Open, 1631 Done, 1632 Closed, 1633 Pending)
-- Own Kind 1650 for time-tracking
-
-Considering to use Calendar: https://github.com/nostr-protocol/nips/blob/master/52.md
-
-- Kind 31922 for GANTT, since it has only Date
-- Kind 31923 for Calendar, since it has a time
-
-## Immutability
-
-Apart from user-specific temporary utilities such as the Bookmark List (Kind 10003),
-all shared data is immutable, and modifications are recorded as separate events,
-providing full audit security.
-Deletions are not considered.
-
-### Timestamps
-
-Mostr provides convenient helpers to backdate an action to a limited extent.
-But when closing one task with `)10` at 10:00 of the current day
-and starting another with `(10` on the same day,
-depending on the order of the event ids,
-the started task would be terminated immediately
-due to the equal timestamp.
-
-That is why I decided to subtract one second from the timestamp
-whenever timetracking is stopped,
-making sure that the stop event always happens before the start event
-when the same timestamp is provided in the interface.
-Since the user interface is anyways focused on comprehensible output
-and thus slightly fuzzy,
-I then also add one second to each timestamp displayed
-to make the displayed timestamps more intuitive.

 # mostr
 
-An immutable nested collaborative task manager, powered by nostr!
-
-> Mostr is beta software. 
-> Do not entrust it exclusively with your data unless you know what you are doing!
-
-> Intermediate versions might not properly persist all changes.
-> A failed relay connection currently looses all intermediate changes.
+A nested task chat, powered by nostr!
 
 ## Quickstart
 
-Install rust(up) and run a development build with:
+First, start a nostr relay, such as
+- https://github.com/coracle-social/bucket for local development
+- https://github.com/rnostr/rnostr for production use
+
+Run development build with:
 
     cargo run
 
-A `relay` list can be placed in a config file
-under `${XDG_CONFIG_HOME:-$HOME/.config}/mostr/`.
-Ideally any project with different collaborators has its own relay.
-If not saved, mostr will ask for a relay url
-(entering none is fine too, but your data will not be persisted between sessions)
-and a private key, alternatively generating one on the fly.
-The key is saved in the system keychain.
+Creating a test task: 
+`nostril --envelope --content "test task" --kind 1621 | websocat ws://localhost:4736`
 
 Install latest build:
 
-    cargo install --path .
+    cargo install --path . --offline
 
-This one-liner can help you stay on the latest version
-(optionally add a `cd` to your mostr-directory in front to use it anywhere):
+## Principles
 
-    git pull && cargo install --path . && mostr
+- active task is tracked automatically
+- progress through subdivision rather than guessing
+- TBI: show/hide closed/done tasks
 
-To exit the application, press `Ctrl-D`.
+Recommendation: Flat hierarchy, using tags for filtering (TBI)
 
 ## Reference
 
 ### Command Syntax
 
-Uppercased words are placeholders, brackets enclose optional arguments.
-
-`TASK` creation syntax: `NAME #TAG *PRIO @ASSIGNEE # TAG1 TAG2 ...`
+`TASK` creation syntax: `NAME: TAG1 TAG2 ...`
 
 - `TASK` - create task
-  + prefix with space if you want a task to start with a command character
-  + paste text with newlines to create one task per line
-- `.` - clear all filters
+- `.` - clear filters and reload
 - `.TASK`
-  + activate task by id
+  + select task by id
   + match by task name prefix: if one or more tasks match, filter / activate (tries case-sensitive then case-insensitive)
   + no match: create & activate task
-- `.2` - set view depth to the given number (how many subtask levels to show, default is 1)
-- `/[TEXT]` - activate task or filter by smart-case substring match (empty: move to root)
-- `||TASK` - create and activate a new task procedure (where subtasks automatically depend on the previously created task)
-- `|[TASK]` - mark current task as procedure or create a sibling task depending on the current one and move up
-- sibling task shortcut?
+- `.2` - set view depth to `2`, which can be substituted for any number (how many subtask levels to show, default 1)
 
-Dot or slash can be repeated to move to parent tasks before acting.
-Append `@TIME` to any task creation or change command to record the action with the given time.
-To add tags or edit the priority or assignee, make the change part of a comment or state update:
+Dots can be repeated to move to parent tasks
 
-- `:[IND][PROP]` - add property column PROP at IND or end,
-  if it already exists remove property column PROP or IND; empty: list properties
-- `::[PROP]` - sort by property PROP (multiple space-separated values allowed)
-- `([TIME]` - list tracked times or insert time-tracking with the specified offset (double to view all history)
-  such as `(20` (for 20:00), `(-1d`, `(-15 minutes`, `(yesterday 17:20`, `(in 2 fortnights`
-  - TBI: track whole interval in one with dash
-- `)[TIME]` - stop time-tracking with optional offset (also convenience helper to move to root)
-- `>[TEXT]` - complete active task and move up, with optional status description
-- `<[TEXT]` - close active task and move up, with optional status description
-- `!TEXT` - set status for current task from text and move up; empty: Open
-- `!TIME: REASON` - defer (hide) current task until given time
-- `,[TEXT]` - list notes or add text (activity / task description)
-- TBI: `;[TEXT]` - list comments or comment on task
-- TBI: show status history and creation with attribution
-- `&` - revert
-  - with string argument, find first matching task in history
-  - with int argument, jump back X tasks in history
-  - undo last action (moving in place or upwards confirms pending actions)
-- `*` - (un)bookmark current task or list all bookmarks
-- `wss://...` - switch or subscribe to relay (prefix with space to forcibly add a new one)
+- `:[IND][COL]` - add / remove property column COL to IND or end
+- `>[TEXT]` - Complete active task and move to parent, with optional state description
+- `<[TEXT]` - Close active task and move to parent, with optional state description
+- `|TEXT` - Set state for current task from text (also aliased to `/` for now)
+- `-TEXT` - add text note (comment / description)
 
 Property Filters:
 
-- `#TAG1 TAG2` - set tag filter
-- `+TAG` - add tag filter (empty: list all used tags)
-- `-TAG` - remove tag filters (by prefix)
-- `?STATUS` - set status filter (type or description) - plain `?` to reset, `??` to show all
-- `*INT` - set priority filter - `**` to reset
-- `@[AUTHOR|TIME]` - filter by time or author (pubkey, or `@` for self, TBI: id prefix, name prefix)
+- `#TAG` - filter by tag
+- `?STATE` - filter by state (type or description) - plain `?` to reset
 
-Status descriptions can be used for example for Kanban columns or review flows.
-An active tag or status filter will also set that attribute for newly created tasks.
+State descriptions can be used for example for Kanban columns.
+An active tag or state filter will also set that attribute for newly created tasks.
 
-## Basic Usage
+### Available Columns
 
-### Navigation and Nesting
+- `id`
+- `parentid`
+- `name`
+- `state`
+- `hashtags`
+- `tags` - values of all nostr tags associated with the event, except event tags
+- `desc` - last note on the task
+- `description` - accumulated notes on the task
+- `path` - name including parent tasks
+- `rpath` - name including parent tasks up to active task
+- `time` - time tracked on this task
+- `rtime` - time tracked on this tasks and all recursive subtasks
+- `progress` - recursive subtask completion in percent
+- `subtasks` - how many direct subtasks are complete
 
-Create tasks and navigate using the shortcuts below.
-Whichever task is active (selected)
-will be the parent task for newly created tasks
-and automatically has time-tracking running.
-To track task progress,
-simply subdivide the task -
-checking off tasks will automatically update the progress
-for all parent tasks.
-Generally a flat hierarchy is recommended
-with tags for filtering,
-since hierarchies cannot be changed.
-Filtering by a tag is just as easy
-as activating a task and more flexible.
+For debugging: `props`, `alltags`, `descriptions`
 
-Using subtasks has two main advantages:
-- ability to accumulate time tracked
-- swiftly navigate between related tasks
-
-Managing a project with subtasks makes it continuously visible,
-which is helpful if you want to be able to track time on the project itself
-without a specific task,
-Thus subtasks can be very useful for specific contexts,
-for example a project or a specific place.
-
-On the other hand, related tasks like chores
-should be grouped with a tag instead.
-Similarly for projects which are only sporadically worked on
-when a specific task comes up, so they do not clutter the list.
-
-### Task States
-
-> TODO: Mark as Done vs Closed
-
-### Collaboration
-
-Since everything in mostr is inherently immutable,
-live collaboration is easily possible.
-After every command,
-mostr checks if new updates arrived from the relay
-and updates its display accordingly.
-
-If a relay has a lot of events,
-initial population of data can take a bit -
-but you can already start creating events without issues,
-updates will be fetched in the background.
-For that reason,
-it is recommended to leave mostr running
-as you work.
-
-### Time-Tracking
-
-The currently active task is automatically time-tracked.
-To stop time-tracking completely, simply move to the root of all tasks.
-Time-tracking by default recursively summarizes
-
-### Priorities
-
-Task priorities can be set as any natural number,
-with higher numbers denoting higher priorities.
-The syntax here allows for very convenient incremental usage:
-By default, using priorities between 1 and 9 is recommended,
-with an exemplary interpretation like this:
-
-* 1 Ideas / "Someday"
-* 2 Later
-* 3 Soon
-* 4 Relevant
-* 5 Important
-* 9 DO NOW
-
-Internally, when giving a single digit, a 0 is appended,
-so that the default priorities increment in steps of 10.
-So in case you need more than 10 priorities,
-instead of stacking them on top,
-you can granularly add them in between.
-For example, `12` is in between `1` and `2`
-which are equivalent to `10` and `20`,
-not above `9` but above `09`!
-
-By default, only tasks with priority `35` and upward are shown
-so you can focus on what matters,
-but you can temporarily override that using `**PRIO`.
-
-### Quick Access
-
-Paper-based lists are often popular because you can quickly put down a bunch of items.
-Mostr offers three useful workflows depending on the use-case:
-If you want to TBC...
-
-- temporary task with subtasks (especially handy for progression)
-- Filter by recently created
-- Pin to bookmarks
-- high priority
-
-### Notes
-
-- TBI = To Be Implemented
-- `. TASK` - create and enter a new task even if the name matches an existing one
-
-# Development and Contributions
-
-This Project follows the [Kull Collaboration Convention](https://kull.jfischer.org/),
-especially the commit message format.
-Currently a separate dev branch is maintained because users regularly receive updates via the main branch.
-Once proper packaging is in place, this can be simplified.
-
-## Local Development Tools
-
-Start a nostr relay, such as
-- https://github.com/coracle-social/bucket for local development
-- https://github.com/rnostr/rnostr for production use
-
-To create a test task externally:
-`nostril --envelope --content "test task" --kind 1621 | websocat ws://localhost:4736`
+TBI: Combined formatting and recursion specifiers -
+for example progress count/percentage and recursive or not.
+Subtask progress immediate/all/leafs.
 
 ## Plans
 
-- Handle event sending rejections (e.g. permissions)
-- Local Database Cache, Negentropy Reconciliation
-  -> Offline Use!
-- Remove status filter when moving up?
-- Task markdown support? - colored
-- Calendar Events - make future time-tracking editable -> parametrised replaceable events
-- Speedup: Offline caching & Expiry (no need to fetch potential years of history)
-  + Fetch most recent tasks first
-  + Relay: compress tracked time for old tasks, filter closed tasks
-  + Relay: filter out task status updates within few seconds, also on client side
-
-### Commands
-
-Open Command characters: `_^\=$%~'"`, `{}[]`
-  
-### Conceptual
-
-The following features are not ready to be implemented
-because they need conceptualization.
-Suggestions welcome!
-
-- Queueing tasks
-- Allow adding new parent via description?
-- Special commands: help, exit, tutorial, change log level
-- Duplicate task (subtasks? time-tracking?)
-- What if I want to postpone a procedure, i.e. make it pending, or move it across kanban, does this make sense?
-- Dependencies (change from tags to properties so they can be added later? or maybe as a status?)
-- Templates
-- Ownership
-- Combined formatting and recursion specifiers
-  + progress count/percentage and recursive or not
-  + Subtask progress immediate/all/leafs
-  + path full / leaf / top
-
-### Interfaces & Integrations
-
-- TUI: Clear Terminal? Refresh on empty prompt after timeout?
-- Kanban, GANTT, Calendar
-- n8n node
-- Webcal Feed: Scheduled (planning) / Tracked (events, time-tracking) with args for how far back/forward
-
-Interfaces:
-
-- text-based REPL for terminal and messengers
-- interactive UI for web, mobile, desktop e.g. https://docs.slint.dev/latest/docs/slint/src/introduction/
-
-### Config Files
-
-- format strings
-- thresholds: auto-send message, time-tracking overview interval and count
-- global and per-relay: username, key location, tag mappings (i.e. server implies pc, home implies phys) -> also get from relay
-
-## Exemplary Workflows - User Stories
-
-- Freelancer
-- Family Chore Management
-- Inter-Disciplinary Project Team -> Company with multiple projects and multiple relays
-  + Permissions via status or assignment (reassignment?)
-  + Tasks can be blocked while having a status (e.g. kanban column)
-  + A meeting can be worked on (tracked) before it starts
-  + Schedule for multiple people
-- Tracking Daily Routines / Habits
-
-### Freelancer
-
-For a Freelancer, mostr can help structure work times
-across different projects
-because it can connect to multiple clients,
-using their mental state effectively (Mind Management not Time Management).
-It also enables transparency for clients
-by sharing the tracked time -
-but alternatively the freelancer
-can track times on their own auxiliary relay
-without problems.
-
-### Family
-
-With a mobile client implemented,
-mostr can track shopping lists and other chores for a family,
-and provide them context-dependently -
-allowing you to batch shopping and activities without mental effort.
-
-### Project Team
-
-sharing, assigning, stand-ups, communication
-
-### Contexts
-
-A context is a custom set of filters such as status, tags, assignee
-so that the visible tasks are always relevant
-and newly created tasks are less of a hassle to type out
-since they will automatically take on that context.
-By automating these contexts based on triggers, scripts or time,
-relevant tasks can be surfaced automatically.
-
-#### Vision of Work-Life-Balance for Freelancer
-
-In the morning, your groggy brain is good at divergent thinking,
-and you like to do sports in the morning.
-So for that time, mostr can show you tasks tagged for divergent thinking,
-since you are easily distracted filter out those that require the internet,
-as well as anything sportsy.
-After you come back from sports and had breakfast,
-for example detected through a period of inactivity on your device,
-you are ready for work, so the different work projects are shown and you delve into one.
-After 90 minutes you reach a natural low in your focus,
-so mostr surfaces break activities -
-such as a short walk, a small workout, some instrument practice
-or simply grabbing a snack and drink.
-After lunch you like to take an extended afternoon break,
-so your call list pops up -
-you can give a few people a call as you make a market run,
-before going for siesta.
+- Relay Selection, fetch most recent tasks first
+- parse Hashtag tags from task name
+- Personal time tracking
+- Unified Filter object
+  -> include sub
+- Time tracking: Active not as task state, ability to postpone task and add planned timestamps (calendar entry)
+- TUI - Clear terminal?
+- Expiry (no need to fetch potential years of history)
+- Offline caching
+- Web Interface, Messenger integrations
+- Relay: filter out task state updates within few seconds, also on client side
