I feel like I didn’t get through most of you considering that this has only gotten 1 vote despite being so much better than a search bar for listings.
If you look at the top left of the second image, you can see that the suggestion is about nesting individual items in different categories. This is meant to be for the likes of scrolls, catalysts, reagents, etc. to be separated in multiple listings, not remain the same.
If this feeling is right, then can anyone tell me what was so wrong in my original explanation and drafts? I can only assume that this was caused by a usage of words that most wouldn’t know, but they’re all pretty common and simple, so I doubt that to be the case.
