- 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)
- Once the importing process starts, only allow the popup to be closed
by pressing pressing esc or clicking the Cancel button, to prevent
accidental clicks
- When closing the popup without clicking the Cancel button, cancel the
import process
