I usually fill chests with certain items and use the 'middle mouse button + ctrl' to get it with the NBT tag.
The problem is that if I do this with another item for example, even if I am not holding the modified chest, the slot that is replaced is the previous chest. And in that, I can not hold several chests with different NBT tags.
In Minecraft Java this does not occur then, I hope to see it fixed.
Another very annoying problem is that I am not being able to use the 'middle mouse button' inside the inventory itself.
