► Reduced app-drawer choppiness by making app-drawer fade-in / fade-out optional (Expert settings / transparent by default)

Please see if this improves app drawer opening performance on your watch. It only affects app-drawer mode, when the app drawer is pulled into view, the background color:
► SOLID = becomes opaque as soon as you start to pull
► TRANSPARENT = constant 50% see-thru during transition
► FADE = progressively changes from transparent to opaque

Thank you Meir Miyara for your feedback regarding these options
