It's a small thing but it has always bothered me that there are two buttons on the shortcut bar.
It would be nice if there was only one button that opened the gui, and the hover vs. hand was a toggle setting within the gui.

Regardless, there's a bug with the buttons as they exist now. Somehow they both communicate to the user that they use the shortcut Shift + Alt + Z, despite one actually using Control + Alt + Z.

You can hide shortcuts from the bar. I suppose I can also put toggles in the settings UI. I won't be making it a toggle between the two though, they can be used separately or in conjunction.

I'll look into that bug while I'm at it. For future reference, please put bug reports on github.
