yep, its exactly what i want!

however, the button seems a bit buggy now. after capturing by tapping between the button and the edge, the button stops working sometimes, until i do a long press on the button.
im having trouble pinning down the exact buggy behaviours, but it seems pretty evident, comparing 0.0.19 and 0.0.20

also, im a fan of making the button bigger instead of adding margins, but im more than happy with the way it works now, barring the bug above.
