I have determined how to turn all other UI elements off or only have then come on when needed. Toolbar, buffs, food/health - it all fades in 5 seconds unless there is an exception. So, I have managed to sort this out for everything except the silly version number.
<boggle> Unfortunately, hiding the UI doesn't do anything besides break the game so is only good for screenshots! </boggle> I appreciate the input, but I'd like a clean UI.
I'd pay someone to program it out for me.
