So, the only way to get the name of a visual seems to be to go to the visual->by name menu and hold down the down arrow. As I understand so far, there is no way to use the auto-change visual function on only the favorites.

I guess a feature request would be a way to directly add a visual to favorites when the visual is playing (i.e. hold a key down for a while). This way, I can add one when I see something I like.
