I personally am of the opinion that as long as people are online let them be. Plenty of people are "afk" by chatting in private chats, working on bios, presets, groups, or just by watching the chat go by. It would be kind of annoying to be working on a preset or something and every hour or so toggle back in just to keep your spot- I personally have multiple tabs open and just watch the chat as I'm working on group related stuff.
