This is a good suggestion.

I, too, would like to see the Select Mode button reseed the visual in a slightly less random fashion. For instance, I often use it to turn off the Trails on Marquesas, but it can take several presses before it does what I want it to do.

Toby, would this be difficult? For the randomization functions, could it temporarily look at what the visual's current state is, and make sure to not randomize it to exactly the same value?
