1. Rating stars on the contact sheets are currently black on dark grey: could the stars be white for faster identification?
2. Currently, using the color class bar to limit the contact sheet view to those images with X,Y, color classes, one has to turn off all the other colors; wouldn't it be faster (or at least an option in preference pane) to do the reverse: click on the one (or however many) color classes and only those images with those choices would remain visible--the color class bar would automatically grey or dim the remaining, non-chosen colors.
