Can you allow for more rows? Since the auto trash doesn't allow sorting, I have it organized by the crafting menu order for my sanity, and ran out of room by the military tab.
Alternatively, a sort button would be amazing!

Rows get expanded as soon as you occupy the last slot, and in mod settings you can change the number of rows and columns.

Hit escape -> Settings -> Mod settings -> Per player tab. The "Columns to display" and "Rows before scrolling" should be what you want.

Sort button: Maybe, but that's quite down the list
