Is your feature request related to a problem? Please describe.
This came about while using the mop remix scrapper - I love the Inventory Slots (Auto) category, but when it's time to scrap, I would have loved to have a category for "all scrappable gear" that I can just right click in one go instead of right clicking Head, then Shoulders etc etc

Describe the solution you'd like
Allow a category to include items that already appear in other categories, regardless of priority.

You don't need a category. Just searching #gear and pressing the transfer button at the top right of the bag window will do that.

I'm trying to save myself the typing (😅) So I guess a "saved searches" feature would help with that. I think there's an issue for that already..?

EDIT: found it #96

I'm ok closing this issue in favor of the other one

Agreed. Since my use case can be solved with #96, I don't currently have a use case that would make this feature make sense.

Yes, the feature request for that is still open.

I'm not planning to add items being in multiple categories. The addon is very specifically designed to show each item at most once, hence the priority system to help with getting an item into the right category.
