 ## Refactoring
 
-- Account settings with `HTabbedContainer`
+- Rewrite the message selection buggy mess 
+
+- Put keybindings in the components they belong to instead of shoving them
+  all in one central file
+
+- Rewrite account settings using `HTabbedContainer`
   - Get rid of all `currentSpacing` stuff
   - Use new default/reset controls system 
-- Split `HScrollableTextArea`
+  - Display name field text should be colored 
-- Composer
+
-- Don't put all the keybinds in one central file
+- Split `HScrollableTextArea` into `HTextArea` and `HScrollView` components
-  - Missing room keybinds (invite, etc) and close failed upload
+- Refactor `Composer`
-- Use QML states?
+
+- Make sure we don't store any state in delegates
+
+- Drop the `buttonModel`/`buttonCallbacks` `HBox` approach, be more declarative
 
 ## Issues
 
-- Forget a room, it comes back because of the "you left" event
+- Popups and room settings can't be scrolled when not enough height to show all
-- `EventImage`s for `m.image` sometimes appear broken, can be made normal
+
-  by switching to another room and coming back
+- `Timer` and `Animation` are bound to framerate
+
+- Handle cases where a known account's access token is invalid
+- If an account is gone from the user's config, discard UI state last page
 
 - First sent message in E2E room is sometimes undecryptable
+  (can be fixed by logging out and in again) (still valid?)
 
-- Pausing uploads doesn't work well, servers end up dropping the connection 
+- After forgetting a room, it comes back because of the "you left" event
 
-- In the "Leave me" room, "join > Hi > left" aren't combined
+- `code` and links in quote ("> http://example.com") aren't properly colored
-- When selecting text and scrolling up, selection stops working after a while
+  in room "last message" subtitle
-  - Ensure all the text that should be copied is copied
-  - Multiple messages are currently copied out of order
 
-- `code` not colored in room subtitle
-- Quote links color in room subtitles (e.g. "> http://foo.org" )
-
-- If account not in config anymore, discard ui state last page on startup
-- Do something when access token is invalid
-
-- Don't store states in delegates
-- [hr not working](https://bugreports.qt.io/browse/QTBUG-74342)
 - Terrible performance using `QT_QPA_PLATFORM=wayland-egl`, must use `xcb`
 - Can't use `QQmlApplicationEngine`, problem with QApplication?
   See https://bugreports.qt.io/browse/QTBUG-50992
+- [HTML <hr> not rendered](https://bugreports.qt.io/browse/QTBUG-74342)
+- Pausing uploads doesn't work well, servers ends up dropping the connection 
+  (no real solution possible?)
