Piecemaker cells must be distinguished from Media cells
When I add a Piecemaker video cell and later go back to edit it, it appears as a media cell.
This is a problem because now I can edit the video's URL which should not be possible since a Piecemaker cell refers to a video annotation and not a video URL. So if I change the URL, the cell is corrupted.
There needs to be a clear difference between both Cell types and in the Piecemaker video cell there should be an edit field like in the AnnotationList cell, not like in the Media cell.
