Description
It is very annoying for tools to get moved all over the inventory when printing. Especially when the printer makes a mistake and your pickaxe has been moved into your inventory or when you get attacked by a mob and your sword has been moved away.

Potential Solution
Perhaps an item whitelist/blacklist so the printer can not move those items in the hotbar while switching out the blocks in your hand to be placed. Alternatively, a slot whitelist/blacklist could also work so the printer can only touch certain slots on the hotbar.

I didn't actually know this, but I looked into this today and noticed that the printer actually already respects the slots that you set in the litematica's pickBlockableSlots setting. So there you can whitelist the slots you want to be used by the printer. The default value of 1,2,3,4,5 seems kinda weird though since most people have their tools there ¯_(ツ)_/¯
