Exactly what I'd like to see too - I have one cab with the full romset so the full list is fine on there but I also have another machine with only 40 of the games I remember playing as a kid.

It would be great to just have the option of displaying only the working/installed roms on the machine.

Installed and working in my cab in less than 5 minutes! Nice, clean interface that even my granny could understand!

Great work guys - I have a feeling that you're going to have a very popular app on your hands here.
