Basically make a wardrobe, similar to construction trophy stuff (depositing stuffed heads or something, idk), but for cosmetic items.
I currently have every single one easy, medium, hard, elite clue item x30 (besides 3rd age and some master clue items) + stuff like santa set, etc. In other words, it takes a shit ton of my bank space.
Random idea about Pali coding a wardrobe where you could deposit all of your cosmetics (acts like a bank - protected by a pin and available only for the respective player, interface looking something like the bank, but with placeholders already being there for you to know what you still need to obtain.
I hope you got the idea and I hope that this wouldn't be too hard to code, but personally I would really appreciate something like this being added.
