- Fixed text wrapping to flow naturally under timestamps
- Changed default nickname to anonXXXX format
- Replaced text with icon representations in status bar
- Added icons to sidebar section headers
- Made autocomplete UI consistent between commands and @mentions
- Added welcome message for new users (3 second delay)
- Changed sidebar header to 'YOUR NETWORK'
- Added command aliases (/join, /msg)
- Implemented /hug and /slap commands with haptic feedback
- Improved command help display with alphabetization
- Renamed 'rooms' to 'channels' throughout entire codebase
