The gobo image library that ship with the Eos/Ion client is a great way to thumb through catalogs, but it would be even better if there was a convenient way to map the filename (0A0B0325-E394-6741-9FCF-1761FCDCB633.png) to a vendor (Apollo, GAM, Rosco) stock number. It would better still to be able get a "where used" view to know which fixtures reference the gobo.
Sort of related to the above, it would be nice to be able to add a "null address" parameter to a conventional fixture (generic dimmer) for things like gobos, manual irises, colour, diffusion so the offline editor can be used as a poor mans "Lightwright" for fully documenting the hang and patch info.
