I would like to see a belt introduced that has utility "sockets".
The grade of the belt and thus number of sockets would need to be rarity/level dependenat with max sockets in game being 7 (or 5 if you consider prospecting and crystal cutting double up and foraging uses no gathering items)
These utility sockets could then be used to store your basic pickaxe, fishing rod, wood axe, shears, watering can & skinning knife.
This is only a teeney tinay suggestion as I know I have enough space and can manage it fine as is but the thought of "hooking" my items to my utility belt has a certain appeal
