I'd like to see some improvements to the User Interface.
Something I find bothersome is that once I log otno Ironclad Online, I can't access settings features, such as keybinds, at least not until I either log off or I'm in a game.
I think Game hosts should also be able to see what other games are available.
I think that people who join a game chat channel (but not the game itself) should be able to see the players who are in the game and what teams they are on, etc.
If you have joined a game and then change chat channels, I think you should be able to see a list of who's in the chat channel.
How about having multiple chat channel tabs?
How about allowing players to be able to see Regular Sins games from Entrenchment?
For the record, I actually think the Sins user interface is pretty good. It's slick and quick for the most part.
