Categories would be a lot more useful if putting items into specific categories weren't so time-consuming. Perhaps when quickstocking, instead of just moving items into your shop, you'd be given the option of selecting which category to put each item in as well.

Considering you can have up to 20 (I think that's the limit) categories, I think it would be really hard to include each one on the QuickStock page. I really wish there was an easier way to categorize things.

Maybe a dropdown box to select a category, and then any items you pick to go to your shop end up in that category? It's not particularly efficient, but easier than going through a dropdown box for every single item.

I'm against making QS any more complicated. I use categories in almost all my shops and it works fine the way it is.

But it would take the Quick out of Quick stocking then c:
