Playmaker is pretty awesome!
I can only speak for myself but I think selecting multiple-transitions would be nice, similar to how you can select multiple states for color settings.
I ask for this because I color my transitions twice more than I do my states and I only start coloring them when there's a lot of transitions in one place. Coloring transitions helps me make sense of all my criss crossing transitions as they flow through the FSM, but right now we have to select each one by one!
thanks though for the great support!
