On the Github it lists a mono font among the styles: "OpenDyslexic, in Regular, Bold, Italic, and BoldItalic. Also, OpenDyslexic Mono, and OpenDyslexic Rounded: intentionally lower contrast." https://github.com/antijingoist/opendyslexic#styles

I do in fact see an OpenDyslexicMono font after downloading it. I can't vouch for how good the font is though, since I'm not dyslexic.

It has, and I use, the mono version. Also, ive seen decent arguments in support of non monospace, as it makes typos of text that should be the same, but isn't, more aparrent when on adjacent lines. But I've been using mono for a while and never had an reason to try non-mono

Oo a fixed-width version of this font could be a great idea! (Am not dyslexic, so am not quite sure if fixed-width will make it more difficult, but if it can be avoided, boom)
