Comment (by ryanscheuermann):

 Well, if that is the case, then I submit my Upload Manager plugin (written
 on top of my patch) for another example of how it /could/ be done.  It
 simply replaces the iframe and provides an "Uploads" options menu.  As of
 right now, I only use it internally for my clients.  I can't submit the
 code (as it depends upon another plugin), but if it's of interest, I can
 do some rework to make it standalone.   And it's not at all l10n'd.

 I've attached a ZIP that contains a few screenshots.

 Its features include:

 * Ability to sort by Date and Name (ASC & DESC)
 * Filtering by 4 options: Images, Files, Music, Video (does mime-type
 matching)
 * Paging
 * Switches the Preview based on toggled options in a manner that is
 visible [not hidden by popup] (see Toggle More Options screenshot - shows
 Gallery thumbnail instead of regular thumbnail)
 * Creates an additional "center-square" cropped thumbnail (Gallery) (this
 is configurable to crop the top, center, bottom, or simply resize to a
 smaller setting)
 * Automatically resizes the original image based on an option (saves my
 clients from uploading huge photos (as in resolution-big) direct from
 their digital cameras)
 * Filters uploads into subdirectories based on mime-type (images, files,
 music, video)
 * Options page that allows you to change the visible options (you can tell
 it to, by default, link to the page using the thumbnail, and then only
 give the end user an option to change alignment - this feature is wholly
 designed for my non-savvy clients - better to make the decision for them
 than confuse with too many options)
 * Intense separation of JS and HTML (basically, the loops output 2 JS
 arrays for each attachment: metadata and options, and then when clicking
 "Insert File", there is a JS function that evals the chosen options to
 create the appropriate HTML) - it was designed to easily alter/hook the
 "insert HTML" methods because sometimes I use Markdown syntax instead of
 HTML.
 * Unfortunately, the downside is that I never coded a noscript method, but
 it's entirely within reason to add this ability.

 Recently (and here's where it depends on other plugins), I've switched it
 to using a "tag" method that is filtered by the_content (in the form of
 <cms:upload name="Moose" id="3" link="page" show="thumb" align="center"/>)
 - but I wouldn't submit that as a core feature.  (This allows me to alter
 the HTML output on the fly without having to find/replace through all my
 posts whenever something changes.  Plus, it looks a lot less confusing for
 my clients who don't understand all that HTML.)

 I'm also working on an Admin level page for managing them outside the
 iframe (but that's still in development).  I would love to see the iframe
 source as a regular old WP admin page with the ability to add new tabs.
 (I'm also developing an "Easy Insertions" plugin to aid my clients
 inserting things like links to other pages, contact forms, mailing list
 signup forms, etc. - would like to do it as an additional iframe tab.)

 I figured most of these features are left for plugin territory, but I have
 no problems with giving back to the core.  Obviously I'd like to see the
 core change in such a way that doesn't cause me to have to redevelop the
 whole thing (which has happened before).  If either you or Andy want to
 discuss this in detail - drop me a line: ryan at concept64 dot com.  I'd
 be glad to help.
