It is currently very inefficient to use the media library. You cannot organize or view in folders (besides uploaded date). Nor can you view more than 20 on a page, which is especially annoying when I want to apply an action to more than 20 (I have to click through each page and apply to all 20 at once).
Our new site already has 250 uploaded images and counting, and the WP library interface is very inefficient! (or perhaps I am not fully taking advantage of it)
