XP Storage System

I've seen a few mods that allow similar things, but I think it would be amazing if there was a way to store XP somehow and put it into bottles making experience bottles obtainable through crafting. This would also pair well with the mending enchantment, because you could have bunches of XP stored up and ready to be used, and when your tools/armor durability gets low, you can use this stored XP and repair all your items enchanted with mending. Along similar lines it would be good for enchanting. It could possibly be similar to item transport systems via hoppers/droppers, where you have your XP storage system connected to your enchanting table or anvil and have direct access to stored XP for enchanting, combining or renaming. As for methods of collecting and storing XP, there might be an item that you need to craft, and when you have it in your inventory this item collects any XP you collect. Maybe it could work like totems, where you need to have it in your offhand in order to be in use. Also it would have a limit to the amount of XP it can store, and when you arrive back home, you can dump this XP into your storage system.
