Pokémon Backpack plugin

Hello guys, I wanna make a Backpack Plugin for my server which serves unlimited storage. It should let people store their in those Categorys: Items, Medicine, Berry’s, Pokeball’s, TM’s and Key Items.

Additionally the TM’s should be ordered in the right order (Number) and you can use the items inside the GUI.

Besides that it would be awesome to use the items in the backpack while being in Battle.
