late reply:
Did you find a solution for sync’ing projects to files?
I’ve been mucking about with a plugin, and I’m something like 50-80% done (I can pull projects from Todoist and create files in a folder defined in a plugin-setting, but the content of the files I create is currently hard-coded. I wouldn’t consider publishing it without adding some sort of templating support.
If there is a solution that already exists, I don’t want to spend more time on it
