Quick-Access Filters in Contacts/Discovery View

[neopiccolorat]

Quick suggestion for the app UI:
Add tappable filter buttons (using existing icons) for instant switching between:

• All (has it is now by default)
• Users
• Repeaters
• Rooms

Hide the search bar by default and reveal it via a single tap (..on a search icon or header).

The actual filter would stay for

Additionally include a filter/view for "Active Discussions Only" that would only show the contacts/rooms with open threads or recent messages. This would streamline navigation when there are many nodes but only a few active conversations.
