The imagination (inventory) is annoying to get used to, especially when you get a new item, it's annoying to get used to the layout. Also it's very annoying to navigate around if you have alot of items.
solution:
Be able to customise your own inventory.
When in the inventory, there is a pencil icon, if you click it, it's as normal but now you can move your items/blocks around. You can make new folders, archive items that you don't like and move items from and into different folders or just without a folder for easier reach. Also a reset button.
