Introducing Bird UI

We also added Mastodon Bird UI, a Twitter-inspired theme.

Highlights

  • Respects your profile’s theme setting (dark/light mode)
  • Subtle deep-purple ribbon for private messages
  • CSS variables for full customization
  • Threaded replies (limited support)
  • Avatars on the left in feed view
  • Unified transparent backgrounds
  • Icons based on Iconoir, Ionicons, and Feather
  • Micro-interactions for likes and boosts
  • RTL language support
  • Mobile action bar at the bottom
  • Color cues for follows and list actions

You can enable it here:

Settings > Preferences > Appearance

Tip: Bird UI works better with the Advanced Web Interface disabled.
