The item_remover_device is lacking many functions that the item_granter_device is already providing, which makes it complicated to build a custom Item Management System like a custom shop.
The item_remover_device is in its current state very limiting as you can only remove ALL Items defined in a list or ALL items of a specified category, but not, as the item_granter_device allows, a specific one from the configured item list.
I think it would be a very good improvement if the item_remover_device gets updated to functional equality with the item_granter_device or at least gets the RemoveItemIndex() function added.
