This is a very small container (slots are 24x24.) It is modified from the StayPut container. Tried to put combine button on top and done button on bottom (reverse of StayPut, ala Remelio) but my combine button didn't seem to be coming through that way, so they are both at bottom.

Basic point is to make containers as compact and immovable as possible to facilitate inventory exploration and tradeskill combines.
