I’m sitting here trying to update well over a dozen entries in my CMS, when I realized how useful a “bulk edit” would be! 
So where I have my huge list of collection items, I could select multiple items, then do a bulk-edit to some of the fields (such as, "Change all these paintings to “Landscape” instead of “Still Life”, or “Mark these selected paintings as sold”). It’s a lot of work to go in and make multiple changes when a few clicks would do…
Just a suggestion!
