You don't have to search the lists separately! You can cmd-click on several different contexts in the sidebar to get a display that shows you the union of the available actions in those contexts. With iPad/iPhone, you'll have to have made a perspective to do that, but I suspect the time it takes to prep a few is dwarfed by the time one would spend tagging everything in the database in the long run. The various programs I use where tagging is supported as a primary way of getting your stuff back all seem to involve large amounts of time tagging, even when adjusting for the larger number of items to be tagged.
