Ability to apply tags to a folder and have anything added to that folder inherit those tags. This was available in Webdam and makes tagging assets very easy on the folder level instead of having to add to each separately. Some of our media library asset folders have thousands of assets which selecting them all has noticeable slowdown and sometimes errors out when saving. If tags could be done at the folder level it would make managing assets easier and more intuitive. Especially when people forget to tag things and over time more stuff is added there can and will be a discrepancy of tags. Obviously we'd still apply tags to each asset as needed on upload, but the folder can at least create a baseline of essential tags.
