Hello dmlavan,
Do you search SlideOut Compass? If not, please ignore me.:P
SH4 Slideout method cause big problem, clickable area is deprived by Slideout item even if it is hide position.
So I guess it is difficult to make a MOD as same as SH3 Huge Compass.
Probably this is not enough for your request, please try #Ex_compass if you like.
