Personally I like to keep things organized so I propose to add folders for equipment in the inventory. For example when you want to equip a tank, instead of Pz4J and Pz4J with a skin you would have only stock Pz4J and by clicking on it you would see a list of all Pz4J variants/skins. It may be even made on a higher level and all simlar tanks could be groupped together (in this example, all models of Pz4).
I’d love to provide some concept “”“art”“” but sadly I can’t launch the game right now. So use your imagination.
I’m not sure if it’s actually beneficial now but if devs plan to add more weapon and vehicle skins etc in the future, it may be nice to have.
