I have a tool I'm working on that is specifically geared towards assisting the transcription of printed books to braille for The Clovernook Center for the Blind [1] built on top of Atom as an extension.
A super-rudimentary basic version will be something I finish when I've the time in the coming months. I was hoping to get some interested from the blind community and get ideas for further OSS work involving that general space (editors).
