Staff client allows you to delete a record and record sets from a set of search results, however, Leap requires clicking into each record, then clicking Actions and then clicking delete (or putting them all in a record set). Right now I'm cleaning up some old record sets. If I were doing this in the client, I have the ability to select multiple record sets within my results list and then right click to delete them in bulk. This would be a game changer in Leap.
