I want to be able to run a query for a playlist item directly from the playlist item, so a button that looks like this:

This will make editing playlists -- something I do fairly often -- that much simpler. Also important to QA/QC a playlist item, as in "what media does this query select?". Right now workflow is 'edit playlist item -> view query -> copy/paste query in to Advanced -> fart around in Advanced query to recreate the playlist item query as-written -> etc.'
