Marco, I suggested ages ago that the Media workspace have an option to show the media items in text format, as per a Windows view of folder contents. Thumbnails aren't that useful (one census citation or form looks much like another), it slows down processing, and to see the full file name you have to make the thumbnails huge.
I think one problem here is that ancestry doesn't have a structured process for gathering and posting enhancement requests, perhaps with priority voting by registered FTM users to indicate how important the suggestion is to the community at large. Developers usually want to give you what they think you need, not what you ask for, unless they happen coincide, I guess.
But the text-only media view is a no-brainer, so I can't fathom why it hasn't been done.
