Is there a way to turn off the anti aliasing of the guides and glyph outline whilst editing? It looks great on a retina screen, but on my iMac it looks imprecise.
The crispness of aliased rendering gives a false perception of precision. Points that are a few units apart appear the same. The difference is a bit like text rendering on Mac vs Windows ("truer appearance vs crispness).
I develop and use Glyphs on a normal screen and it works fine for me. I hope you get used to it, too.
