I agree about the principle of least privilege, but the problem is that almost any accessibility app must basically be able to simulate user input to function, i.e. for a cursor app to actually provide a cursor, it must have the permission to activate any UI element on the screen.

I trust Quick Cursor, but I shouldn't have to - since basically every smartphone now is too big to use with one hand without having to shuffle it around and risk dropping it, I think the cursor feature should be built into the OS.
