I have a general question: is it possible to use the new WordPress 3.5 Media Uploader window for other purposes (i.e., as a modal popup window for content)? I would like to do this and have spent a lot of time trying to figure out if/how to do it but have had NO luck.
I'm basically looking to replace the Thickbox popup as the way my shortcode panel is presented in the admin panel.
Has anyone done this or something similar? Can anyone point me to something that covers this or some variation on the theme?
