Describe the feature

Putting Cosmetic items in their own category would be nice. Is there an API to detect them to avoid a tooltip parse? I'm having to study the Junk section for the pink corner tabs on items to make sure I don't vendor cosmetic items that I haven't learned yet.

Describe the implementation

Probably an option to do this, like that of the new per-expansion categories for reagents. Right now I'm doing this manually by dragging cosmetic items to a custom filter.
