As you all know, the market place could use some improvments, and here is one.
When adding an item, its annoying that you have to add only one item each time, so i suggest when pressing add item, you will be able to select up to 10 items (full inventory) and add them all at once, and then automatically it redirects you to a page where you can edit those items.
Second one is that you can have the abillity to remove or delete more than one item at once from your shop.
