I know there have been threads suggesting more organization for assets (bulk upload, folders, keywords, etc.), all of which I support and have voted up, but I would like to throw another hat into the ring. I think we also need a bulk delete option too. I have swaths of images that were only used in tests or for designs that were never approved, and deleting them one by one is tedious (I should know, I just wasted time doing it yesterday). Giving us more control over the management of assets would make the user experience much better. I'm sure I'm not alone in thinking this.
