As the author of the plugin I take a couple issues with what you’ve considered a review here. First, just because you personally don’t see the purpose of a plugin doesn’t mean it deserves a one star review. Second, WordPress core only lets you insert media into the editor. This plugin gives you a separate meta box with any fields you want, to keep the list of Attachmemts outside the main editor. Next: this plugin stores everything in a single metadata record, so I’m not sure why you’ve felt the need to speculate that the plugin runs a ‘large amount of potentially useless queries’, I’m not really sure how to respond to that without saying that the plugin might run a single query for one metadata record if you tell it to.
