Don't know how hard that would be to implement, but it sure would help me (and I'm sure a few others) out!
I love playing as many machines as I can and keeping track of them, to me, is almost just as much fun as playing them. Being able to sort personal scores by machine name would help me be able to delete and re-enter a new high score for a pin (seeing as how, in my case, I do not like keeping more than one score there).
Should this be doable, it would be greatly appreciated (at least by me)!!!
