OLD

- Refactoring
  - Migrate more JS functions to their own files / Implement in Python instead
  - Don't bake in size properties for components

- Bug fixes
  - Past events loading (limit 100) freezes the GUI - need to move upsert func
    to a WorkerScript
  - `MessageDelegate.qml:63: TypeError: 'reloadPreviousItem' not a function`

- UI
  - Invite to room
  - Accounts delegates background
  - SidePane delegates hover effect
  - Server selection
  - Register/Forgot? for SignIn dialog

- Client improvements
  - Filtering rooms: search more than display names?
  - Initial sync filter and lazy load, see weechat-matrix `_handle_login()`
    - See also `handle_response()`'s `keys_query` request
  - Direct chats category
  - On sync, check messages API, if a limited sync timeline was received
  - Markdown: don't turn #things (no space) and `thing\n---` into title,
    disable `__` syntax for bold/italic
  - Push instead of replacing in stack view (remove getMemberFilter when done)
  - `<pre>` scrollbar on overflow
  - When inviting someone to direct chat, room is "Empty room" until accepted,
    it should be the peer's display name instead.
  - See `Qt.callLater()` potential usages
  - Animate RoomEventDelegate DayBreak apparition
  - Room subtitle: show things like "*Image*" instead of blank, etc

- Missing nio support
  - MatrixRoom invited members list
  - Invite events are missing their timestamps (needed for sorting)
