Administrators have the right to lock a smart list so the users cannot edit the filters. Like creating your own System Smart Lists or similar functionality when you share a smart list with another workspace and it creates the read only function (but with that one you can't use the asset). We have a variety of smart lists that we NEVER want edited, and even go so far as to put "DO NOT EDIT/DELETE" in the naming convention, but through the general nature of people they always seem to get edited anyways.
I would think this would already be an idea somewhere, but I searched for a while and couldn't find it.
