i think I saw this idea somewhere or it was slightly different but here it is
spend like 100,000 gold for a whole new window in the inventory (max 3). To add onto this idea, every time you buy one, the next one gets more expensive. Click an arrow (<- ->) below the inventory box to flick through your hats and weapons. Also if you click and hold down on an item in your inventory, you can drag it into a different spot. This way you can have a window for hats, a window for weapons and a window for novelties/holdiay items.
*note
The idea about buying a whole new window was the one i thought i saw (but cant find), the other ideas are the one i thought of :D
adding a whole new window is too much invo space imo. unless someone wants to own every item and some duplicates....
yeah thats the point lol.. even if some of the items aren't that great i'd still like to own one haha
