This GIF is demonstration that new items can be created and added to the inventory, the current inventory have the auto sorting system activated. The player can freely swap the position between two items if they wish to.
Sorting might seem useful to many, but there are times where it is quite irritating. Therefor I've added a toggle to disable it if the player wishes to. On the right is an example of how it works with or without the sorting toggled.
This isn't used much for inventory items but it could be quite useful if the script is applied to the inventory windows itself. Having the ability to move windows around just like operating a computer and move folders around.
This is made months after the other features therefor the layout seems very different. The main feature here is just a window. I added the ability to resize and move the window, making sure that the game remember where the last position was.
