Currently, unless you are ESO+ which I am, if you are not, you just have one bag. For ESO+ you have an unlimited crafting bag. With the login rewards. Why not add a 3rd bag, but just for crown related items, either bought from the store/crates or rewards. Such as those exp scrolls, poisons, repair kits, etc. That way it is not taking up regular inventory space, and less likely to just be destroyed. Once you get enchanting maxed out as an example, do those poisons have any use? Or once you max provisioning, and say you are pure magic. The blue crafted quality food that boosts health and magic give higher stats to those 2 than the foods that boost health, magic and stamina. For someone totally new though, or if you are rolling a new alt, those poisons, and 3 stat foods would be of more use. Perhaps make a 3rd bag, for these items. So down the road, say you make a new char, and you have 2 150% exp scrolls, some food buff items, etc. You would actually put those items to use if you could bank them in a Crown bag.
