Hello fellow survivors!
A QoL change that I feel everyone would benefit from even if it hasn't come to mind yet is a change to the modification screen for Items.
Instead of having to find an item, press modify, click the mod off/on the item, then having to confirm the change feels like a chore. My suggestion is to have it in such a way where you click your item, then be able to drag and drop mods on and off items. This would make the interaction seamless, quick and super convenient; especially when you find an upgrade while looting you can, boom, on and off or switch around you mods and paints! LMK what you think!
TLDR; Make it so we can drag and drop modifications on and off items
