So I find it annoying to have to find a specific item in my huge inventory, especially when I desperately need a berry or nut to keep from dying.
Solution - a radial menu show only items you can equip (maybe with a scroll within the radial menu to limit size) I imagine like the bombs/items in Witcher 3.
Mockup of what it would look like
I imagine it would behave like the resource scanner, except that there's too many items, so maybe hovering over the "body" section and using the mouse wheel, you can select from the subsections.
It's up to you guys how bulky / how many "sections" can be shown... I was thinking major categories - Health, Tools, Weapons, and Body, but others such as "building" for miners or color guns may be nice too... Your call.
