Probably not for MVP, but later we should also consider adding the commands from bnet 1.0 to make things easier for people who are used to it.

eg.
/friend add
/join
/whisper
etc.

Current progress: #35

List of possible future features (don't have to implement them all, just a few that popped into my head while thinking about chat channels):

• list of all public channels
• preserve the list of joined channels for each user
• save X amount of last messages on the server for each channel
• group/classify channels into public/private (password protected)/special etc.
• configurable options (eg. for show/leave notifications, timestamps etc.)
• channel operator system
• ability to kick/promote/demote/ban etc.
• chat commands (eg. /friend add name, to add a friend)
• invite a friend to a chat channel
• focus text box input at all possible times (basically, keep the text input field focused as long as it doesn't break expected behaviour)
• private messages (should work both as /whisper in battlenet 1.0, as well as open a new window with just you and a person you're whispering with)
• save private messages on server in case one user is offline (so he'll get the message when he signs in)
• status icons (online, away, dnd, in-game (type of the game he's in) etc.)
• emoticons! (hopefully we don't overdo it with this and only add cool, bw-related ones)
• highlighting (sound and visual notifications)
• pagination for list of joined channels
• syntax for linking various things (html links, game lobbies, profiles, teams etc.)
• auto-completion (of commands, user names, channel names)
• add an option to allow people to read history of the chat before they joined

Some suggestions:

• override select all shortcut to select only the text box input
• option to minimize offline player list
