categories which you can turn on/off would be nice. like: crafting skills, quality range where you can add numbers, same for durability, and for sure a search bar to find exactly what ppl looking for.
if we gone have NPC's soon we could have a NPC for gambling maybe? it would remove items from the game as well. lets say i can give 10 blueprints to a npc and get a random blueprint back, that would be a nice option. especially for the stacks of cart prints which will never find a use.
