 This is a WIP and mainly meant for my personal use. Heres some things you might expect to work that don't. Plus some other things I should mention.

 - Only shows existing chats
- Only fetches a few old messages
- No incoming message notification / count
+- No unread message count
 - No proper connection drop handling
- No uploading of images/video/audio/data
- Not configurable at all (except through your terminal settings)
- Leaves its config files in your home folder
 - FaceBook obviously doesn't endorse or like these kinds of apps and they're likely to break when FaceBook changes stuff in their web app
