i dont see a rotating option ever happening. for one, a main point in the game is the player figuring how to fit things. second… the logistics of getting clickpoints and functionality to flipflop at will would probably require more coding than is worthwhile.
now… perhaps some craftable buildings that are new, and have two versions… maybe. if they determined it would be worthwhile to code up front (and not have to redo all the buildings in existence) then you'd be able to perhaps select a "right facing Special Doohicky" or "left facing Special Doohicky". maybe even give then cute names that explains why there are two of the same but not the same.
