I just have a bad habit of ruining stuff too far

I work as a high school teacher who teaches Digital Design. I have kids constantly making new frames and I'd like to keep them from doing so. Can you add a feature that keeps others from adding frames without your permission?

Should be able to set mouse buttons for keybind shortcuts. I want to set MMB to hand tool, etc.
