i use a mod that moves my hotbar up some so it floats a little above the edge of the screen. i'd love to have appleskin float with the mod so it still lines up. it could be as simple as a "raise up the stuff by this many pixels" slider. i just really wanna see this compatibility so i can use the mod's full list of features.

That mod can add compatibility using HUDOverlayEvent from the AppleSkin API:
