Suggestion

Allow the emitter to be placed on any sides of the storage block (or barrel) and have it rotate. One reason is top side of storage blocks is needed by mods like "create" for the chutes and has no alternative, also some build designs might want the emitter hidden but the barrel shown.

Implemented in 66f1188. All three sculk item transporters can now be placed on all sides.
We will release an update with this and other fixes & improvements in the very near future.
