Maybe I’m missing it, but it would be nice to have the Easel display match the wasteboard in using cm as the grid-lines. As it is now the preview has markings for inches, and if I want to know where that is in actual space on my work-area, I need to bust out my tape-measure. Seems like an accessibility issue to me, so that’s where I’m posting it.
At the bottom of the art board area you can change from inches to millimeters. Is this what you are looking for? It’s right next to the magnifying glass plus and minus icons.
