Perhaps this is because I'm using MV instead of MZ, but I have found a couple bugs.

The first is that the vertical position of the control button cannot be set. It is always stuck to the top of the screen.

The second is that the buttons do not disappear when messages are showing like the option says they should. Instead, they just become unactionable. You can press them and they won't do anything. Even with the option turned off, it seems that the control button doesn't work to hide the controls if messages are currently being displayed, which is unfortunate.

Thanks for making this plugin! I'll shoot you a bit of cash if these two bugs can be fixed because it is pretty much perfect otherwise! I'd also love it if there were an option to lock the position of the buttons within the game window, but it's not a huge deal at all! I might also suggest a way for the buttons to disappear if input from another source is detected, such as if you're using a gamepad or a keyboard.
