Ah I see. Great job on the way it currently works though, I love seeing that quick shift from an untidy mess of me picking things up into smooth layers.
On a side note both the sorting and the general use of stash boxes would improve if it didn’t have 17 rows. Nothing goes into 17 so things always end up wonky.
Lol I know, it bothers me so much. That and also how the sort doesn't put 1x1s side by side to make a pair so you don't get that awkward 1x17 section down the right side. We just hired a dedicated UI dev for the first time to redo all these janky old bits of my code floating around.
