If you are looking some ones showcase for furniture or any other items it shows how many they owns. But sometimes we don't know how much we have in our showcase. I like to have a text [YOU OWN ##].. Take the below img as refence
Hmm imagine if you wanna buy something bulk that are many us feel like to buy from a seller so every time you go check your show case if have that one or not is not annoying then it's fine
Imagine you need/want to go the the shop for 1 specific thing. But you have to walk around the shop to find it and see if they have any left. Aww fuck such a hard life having to actually do something for the things you want. It takes 2 seconds to search for something in showcase
