I think a neat upgrade would be one where it always keeps 1 item remaining in the slots so you don't accidentally empty the drawer entirely. Alternatively a filter similar to how Thermal works, where you set which kind of item the slot should accept so it always displays the item's icon regardless if it's empty or not.

I absolutely despise the vanilla chests so this mod has been a life saver 🙏

I think you dont need to keep an item.

Yust lock the drawer, and it will remember the item that was stored there.
