Describe the solution you'd like
I would like to be able to get some of the different options for skins without the skin being visible. I would love the sponge or diamond/netherite upgrade, but I dont like the way they look.

Additional context
Perhaps make a separate slot for skins and "skin upgrades effects", or a toggle that allows you to say "always show leather skin" inside each backpack individually?

Currently the only option is to hide backpack entirely - you can do that by entering backpack settings (cog icon) and clicking eye icon (when backpack equipped).
