Most of the features you would expect from a chat application are missing right now
but we are getting close to a more feature complete client.
Specifically there is support for:
- User registration.
- Creating, joining & leaving rooms.
- Sending & receiving invites.
- Sending & receiving files and emoji (inline widgets for images, audio and file messages).
