co-op advents chat tab

I have suggestions that I would like players and BB to think about, and possibly even consider as a good idea to enhance game play.

First, if players are active on an adventure, their avatar could show up on advent island, this could help see who is actually present, which would be nice, and they also could be asked to leave while some blocks are being set up, this may even help reduce lag during blocks.

Second, how about a advent chat tab, for multi player advents, so all players can chat between themselves while doing these advents.
