I see in many online demo and/or tutorial videos that the wx4.set screen is a light grey background, which I like. But the version of wx4.set I'm using is the darker grey. I do see that the Engrave_Marking.set screen is the light grey screen. Where do I find the light grey wx4.set screen?  In the demo for the Touch Module Mach 4, for example it is a wx4.set screen in light grey. Is it because it was modified by Warp 9?
