multiple colour flags for images - making it easy to see at a glance which images are with which agencies. This feature is available in Darktable .

At the moment only one colour label is allowed per image. I t would be really useful to be able to assign 5 or 6 different colour labels so that large stock collections could be managed with each colour label represents an image library or agency. This would make it very easy to see at a glance where images are represented, especially where a single image may be with multiple agancies.

The idea is similar to the little coloured circles used to do this job on slide mounts back in the days of film.

The feature is availble in Dark Table - but not a greaat implementation - ideally labels need to be a bit bigger - same size as stars. Screen grab:

No other image management software offers this.
