In Recipe scan, it would be awesome to see the number of items (Quantity) the character has already listed on AH or in bags.
This will allow avoiding crafting items that already exist on AH (Listed) or in bags (Crafted)

Allow setting a "Max qty" filter so the Recipe Scan window doesn't show recipes for items that already meet this criteria.
e.g. After I craft 40x [Infurious Hide], I can set max qty in Recipe Scan to 40, so [Infurious Hide] wouldn't show in results

I'm not sure what addons allow API to get number of items, but TSM does that for sure
