We'll , I thought of this a long time. Since there sets to organize you item's why don't you make a mini set? The mini set can be added to a set to make it easier to organize like how folders can be added in a folder . This will help everyone in my opinion.this is the ultimate way to make ToriShop items (inventory) easier and stronger.
My inventory is very well organised btw.
I have a set for every color.
Just buy 70 sets and name them after every color. Now with the new upgrade, where u can't see empty sets, it's even better.
