Now iPadOS has very rudimentary mouse support through the AssistiveTough feature. Perhaps it would be nice to make use of this? Currently, in the presentation mode the mouse cursor is hidden, along with other interface elements.

While GoodNotes 5 already has a very nice laser pointer feature, this still requires you to be near the iPad. On the other hand, when doing a presentation, the ability to move away from the podium would be very nice.

I happen to have the Logitech Spotlight presenter, and it can actually move the mouse cursor, when paired with my iPad Pro. So, it would be really nice if you can build an option to reveal the mouse cursor during the presentation mode if 1) the AssistiveTouch is on and, 2) the mouse was active anytime during last s seconds (so, if the mouse was inactive for s seconds, the cursor would be hidden). Perhaps changing the cursor shape to the laser pointer would be even nicer.
