So since we have nbt command for doing basic stuff with nbt data, I think it would be cool to implement some kind of gui that would offer more options for nbt data like editing, showing exactly all nbt data and so on. It could even simplify nbt editing somehow to make it easier to edit nbt data. Like having all possible nbt data variations so you don't have to remember everything. Currently there are like nbt editor outside of the game but having something directly in-game would be better solution.
