Future
It's possible to constructe HTML pages + vue-github components to dynamically represent the state of a "roadmap" as seen across multiple GitHub projects (aka repos).
All the open milestones from {{user}} / {{project}} + their
descriptions which may include vue-github markup for issue lists from
other repositories. Sadly, there are only two sort options:
due_date and completeness.
This milestone is chosen entirely via markup and could be from any public GitHub repo. It also includes the "embeded" markup from the description of this milestone (if present).
Also completely declared via markup and with it's output build from a custom template partial.
