With this datapack is it possible to store XP, on your player account, without standing on a block or something!
And to restore it with your XpStorage menu, to get the menu rename a water bottle to "XP Bottle" and that's it!
And with this datapack is it possible to trade experience to each other, your full XP bar or some several points.
Watch the video to see it, or watch all the pictures :D

Gamerule sendCommandFeedback: true/false, important if you don't want all the extra messages!
Bug: points are not always the same, sometimes minecraft says you have 0 experience, but you have 1 experience in your bar, use the bug function, to fix that! Watch the changelog for more information!

Important:
This datapack works with all minecraft levels, but if you go higher than level 2000, and you store all the 2000+ levels of xp, you will lose some experience points and you need to use the all function twice, because the all function do max 2000 levels each time! For trade is it possible to trade max 90 levels each time! And the points are not going higher after level 2000, because my datapack tracks all the levels under the 2000! But that's no problem because your store 2000 levels max each time, not everything!
