From the main forum area:
I like the specialised containers, but you're effectively paying more money for a less-useful container, since it can't hold everything and you end up with unused space in your inventory. I'd like them to have some extra slots (say, 24 instead of 16). I'd also add some more specialised containers, like these:
Mining sack, which would automatically collect my ore when I added it to my inventory and had a few extra slots.
Icebox, which would automatically collect food, also with extra slots.
First aid kit, which would collect potions.
Any other suggestions?
