honestly this would be really nice for organizing for example, marking which items you need during a subeta event and rather not clutter up your public wishlist or marking for yourself "these are the cws I have released" (because I know some people also do that, and maybe they want to make the list private at some point) idk I feel like there are several good motivations for making certain wishlist categories private, even the unsorted one

I'm not sure if this would be easy to do (add a non-default feature you have to switch on in a wishlist category to set it to private viewing only, or friends only etc), but I hope it would be :3

Yeeeeeees I support this. I never know what to title the categories I don't want people bothering to look at...

Making wishlist categories private. There's already a topic about this. :)
