The world has tons of containers to search - that is awesome. Many of them have nothing in them - that is fine. having to click on every one to have it open to show it's empty then closing it back - that's not fine and a horrible time sucker.
If the container is empty could it please tell us so on hover please. Thank you.
Yes. If they really want the visual clutter, please convert many many many of these vases into non-lootable vases. It's so tedious to look in everything. Some kind of aoe open nearby containers would also be rad.
