Muc aka Group Chat has been something that’s been in Monal since the beginning. I’ve decided to throw out all the old UI for this and remake it. The old version was something I wrote before I had very many users and based on my experience using pidgin/adium/gaim. It doesn’t work anywhere near as nice as I would like it to. Also given the greater importance of group conversations these days, I have decided make it a top level item. There isn’t a lot of room for things on the tab bar at the bottom. I think this is what the current four will be.
