This would be quite nice… I like to keep things tidy BUT the way it is generally forces me to do only occasional deep cleanups and then let it ride for a while. Something that does seem to help me is to have set locations for items I always carry. But that only goes so far.
I actually kind of like it the way it is. It actually FORCES me not to sperg too hard about inventory management, which is definitely a good thing in my case, as I’d otherwise be the most aggressive inventory-nazi ever to walk the earth with regards to my own inventory.
What gives me the most trouble is when I use two types of block that stack together in two hands, than I break one and pick it up but it goes to the other hand stack and than I have to go and rearrange stuff in stacks.
