In the last month, while preparing to the big launch of the media area, we've shipped a handful of features that you have requested!
Here's the summary:
Content Delivery API explorer directly in the CMS interface
ability to rename uploads
added metadata to uploads, e.g. copyright, author, notes, custom metadata, etc
editors that have publishing capabilities can see details on deployments
added a link to go from model settings to collection/instance
Bear with us a little bit and we'll be in touch soon for the big release of the media area!
