- Refactor everything about HBox, and adapt all the pages and popups
that used it
- Replace HTabContainer by HTabbedBox
- Make boxes swippable
- Make esc presses in boxes click the cancel button
- Make all boxes and popups scrollable when needed
- Replace generic apply button icons in popups
- Fix tab focus for error and invite popups
- Rework (still WIP) the account settings page:
- Use the standard tabbed design of other pages
- Ditch the horizontal profile layout, hacky and impossible to extend
- Add real-time coloring for the display name field
- Implement a device list in account settings (Sessions, still WIP)
Use native ListModel which require a lot of changes, but should be
much faster than the old way which exponentially slowed down to a crawl.
Also fix some popup bugs (leave/forget).
Not working yet: side pane keyboard controls, proper highlight,
room & member filtering, local echo replacement
