I'm also one of those people who like to have a clean interface. I'd like it if certain things can fade away when unused, like the submenu on the bottom right!

An automatic minimizing/collapsing chat box would be nice too! So when the chat isn't being used, it slowly minimizes...? Or just simply fade maybe, like when in cutscenes! Of course, these should just be options for the players to toggle instead of permanent, set stuff.
