SFML v3.0.2
I hadn't realised until this weekend, when working in a very dark environment, how annoying the current GO button's lack of illumination is.
I was running the whole show from a stack, and even when 'waiting for GO' the actual button is dark and only lights up when it flashes during a fade between stack steps.
Surely it should be fully lit at this time as it is active? And then flash when crossfading.
