Hiyaaa!
Could you dear devs implement fast switching for traveller's sacks when using a belt?
Example situation: grand belt with pickaxe, 2 sacks in hands. You are trying to mine, pickaxe swaps with sacks. You want to pick all rocks from ground, you are getting inventory full, but you have to swap manually sacks with pickaxe now, to have more space in inventory for rocks. Same thing with farming for example and couple other jobs. Just when you want to pick something, and you have no space for it, sacks should just swap automaticaly if they are on the belt.
