Hmm, I think it’s the same in Triton.
The information in the status bar is positioned with explicit values. If you hide the button you get https://i.imgur.com/1fStf2T.png which looks a bit lopsided. If you reposition everything it looks okayish: https://i.imgur.com/x0cWqi8.png
I have no strong feelings either way. Heh, this might be because I don’t dock the menu!
Maybe clicking the menu button should switch back to menu mode?
