I use "Vertical Scrolling" in Portrait mode for all pieces I play. And usually, I want to turn full pages at a time. But there is one piece in particular that I want to only "use half-page turns". Whenever I play that piece, I have to be sure to remember to switch the Global Settings->Use half-page turns, and then remember to disable that setting when playing anything else.
Probably from a UX perspective the "Use half-page turns" checkbox can be moved from "Global Settings" to "Default Settings", and add an override in the "Piece Settings" section below it.
