I've seen a couple of posts on this but I thought I'd give my two cents and maybe expand a little... (sorry if this has been covered in past posts or through dev feedback)
__Storage UI: __
attempts to overcome scrolling
Default setting
- storage categories default to fully collapsed
OR - a memory buffer to recall a user's last input (i.e. if I collapse my categories they remain collapsed and saved to the player file)
Sub Tier Categories
- Species type lures*(e.g. Big Game, Avian/Birdlife)*
- class specific ammo (e.g. 7 -9, 4-8)
- class specific weapons (as above)
Hide/Filter/Search
a search or filter feature for rapid access to specific items and help filter out unused items
Sell-back/Exchange:
Admittedly the sell-back idea has the potential to be abused making the idea unfeasible, but an alternative could be to swap/exchange an item, like-for-like (e.g. tents/blinds/tripods), but for a different color which would help simplify storage
