For both android and ipad.. even on the ipad pro 11 this was always annoying, on the S9 ultra more so because you have to move so far to tap the X or check mark when masking on a tablet. I edit in portrait orientation. Moving the X and check mark button might frustrate users who've gotten used to its location, so what I am suggesting is to add an additional X and check mark UI buttons on either side of the masking/healing ui interface as in the screenshot attached, it'd be a great improvement to UI useability. Additionally is it possible to assign a pen gesture on the S pen to accept or cancel? Like the side button click for accept, double for no etc?
