A button that shows if a player is online or not...
It would be great for people to see if their friends or other people looking for a party were online. Go with green for ol, yellow for idle the past odd-so minutes, red or black for offline.

This is a good Idea as well, also set a time if you need to leave game for something, that time out for your character guarantees your not booted and could set an ai for the team. say to go to the restroom or even step out side to talk to the mormons, you never know after all. so setting that option aside for online and offline functions in the game would really be helpful
