Finding a desired category in an advanced search is currently a nightmare, especially on mobile. If there were either collapsible parent categories or the ability to search for a category by typing in the name via a search bar like on the Crystal Commerce Inventory>Products in the admin panel would be great. Having to scroll through a list of every child category for each product is miserable. The category box for advanced searches also shows up as an empty white box on mobile so it's unclear that it's even the category search. Making this more user friendly would definitely help drive sales.
