If you want me to add an option that rejects any mouse clicks for page turns or activating the overlay while in performance mode, I should be able to do that as I believe I can distinguish mouse clicks from taps or swipes. I'll have to see if ESC would be an option for reactivating the mouse.

Thanks Mike, it would be very good! That's I mean indeed: "activating the overlay while in performance mode".
Concerning the ESC key it was just a suggestion, any key or combination of can work for this purpose.
Looking forward to it. Thanks!
