I had a feeling I'd got that @rse about face, but I did update Columbus via app manager beforehand.

I have noticed though, that when I start the app, the full screen toggle icon is up near the top left of the screen with the menu button above it. Once I tap the screen they expand to their rightful positions.

I can't post a screenshot because it doesn't happen when the keyboard is open. You'll just have to take my word for it.
