I would like to be able to extend the media manager interface from plugins without using JS. A first feature would be adding rename/move support for (individual) media files in the move plugin or also moving or renaming media namespaces (both is already implemented in the plugin, it just needs a user interface). Furthermore the tag plugin could be extended to support tagging media files (though that also needs FS#474
and a media metadata index). I think a first step could be allowing plugins to add additional tabs to the interface and to wrap the different parts of the interface into events so plugins could add HTML code before or after the different parts or also replace the main part.
