i just wanted to post a quick note to say that the mouse settings are listed in the documentation here as well as my vm as being in their own directory (/boot/system/preferences/Mouse), but they are in /boot/system/preferences/Input instead. the graphic on this page shows the correct place to adjust them, but lists that incorrect directory. the config directory is the same as on that second page.
it is certainly not a big deal in the scheme of things. it didn’t take me long to find what i was looking for in Input. i just figured i would mention it in case it helps
