Well, as one never knows what might be interesting for whoever, I've only implemented what's important for me smile. So the answer is no, but all the information that you'd need for it is available in files produced by QMC2 (besides the machine list database, there's also a favorites list and the ROM status cache - both text files).

On the other hand, the ROM status export feature already supports most of what you want, it just doesn't honor "favorites" yet. So if you create a feature request for adding it to this feature I might consider it.
