Exp storage

I believe we should have a way to store our levels in game. I don't think we would have to add a whole new item and etc. or mechanic i should say. But maybe like using the book and quill to log exp, maybe you have to use the same crafting recipe as the locator compass but the book and quill. I don't have a name for the item but maybe like "log book" or something simple. 

I like others ideas of storage tanks and etc. but I know that probably doesn't fit the whole mc base game vibe. That's why I think the book and quill are a better option because its recognizable, I believe it still has that Minecraft feel to it, encourages players to explore, and gives us a new mechanic. 

Too if you want to have it not be "super over powered" make it have a limit on how much exp and give it the ability to be upgraded like a adding paper to a map or adding enchantments for it like "Storage 1 , 2 ,3" 

If anyone or Mojang reads this, thanks for your time.
