Having to re-do a browse for a single changed item isn't too great, so the less of that, the better. That also means that I didn't waste my time when I added proper change support to optical-media ;) Although, that won't work with added though, as either you'll pass the GrlMediaBox that contained the added item (meaning, "you need to browse this again") or pass the new GrlMedia which is fine if you know that you don't have any children items in the source but is useless otherwise. Should I file a bug about this? I'd fix this by adding a new grl_source_notify_change()-like call, deprecate the old one, and still send out the compat "content-changed" signal. > > Should grl_source_notify_change() warn if the GrlMedia is neither %NULL > > nor a GrlMediaBox? > > > Right now, I don't think so. >From the above, that makes sense. > > 3) Finally, I wanted to be able to add thumbnails to items retrieved > > from the Tracker plugin.

Maybe an explanation of what GrlSource needs to be passed to grl_source_notify_change() would be useful.
