I really like that you can click on "Upgrade to Champion Permanent" even when you don't have enough Champion Essence and it then shows you how much Essence is missing until you can unlock it.
I don't know if it's a bug or intended that this is not the case for skins and you simply can't select "Upgrade to Skin Permanent" and thereby can't see how much Essence is missing to upgrade the skin shard.
Would be great if this could be fixed/added.
