My idea pertains to how a user's shop stock works.
I think it would be very beneficial to categorize the stock page according to an item's type. My shop currently has over a 100 items and I can only imagine how hecktic it can be for people with hundreds more. I was thinking a list could be made either out of links or a dropdown with possibly the number of items in each category as well. (Of course if a category had no items in it then no need to display that one)
Something like this for the links:
Battle Magic (3) | Grooming (5) | Gross Food (10) | Toy (20)
It seems like a very easy idea to implement, in my opinion.
Thank you for your time, and I look forward to this being implemented.
