It would be useful to be able to be able to turn off all labels in a contact sheet (ie. no filename or separate color label/rating line) so that it presents just a clean page of thumbnails. So far as I can tell, there is currently the option to add up to 3 labels in addition to the filename, but no way to disable the filename line. Perhaps the color label could be used for thumbnail border, or info is available on rollover.
This would mostly be useful when sorting small thumbnails with many images on screen at once--it's less of an issue when using larger thumbnails. It would be useful, for instance, when creating a custom sorting order of similar images shot out of order in order to group them together for keywording, etc.
