This was someone's project I just saw and thought "hey, I could use this" and so I've been working making the wood movable in the inventory slots. It is no where near done. The wood doesn't move inventory places well at first, but if you move it around a bit it starts working just fine. DO NOT PLACE THE WOOD BETWEEN OR OUTSIDE INVENTORY SLOTS!!!!
No where near done. My technique for this is very complicated and takes a long time. If you are seeing this now, just know this probably will not be done for at least another month. Most likey a year.
