Project dependency tracking

[jbenet]

It would be fantastic to be able to track dependencies across all the dozens of repos and thousands of issues. It would be fantastic to see what's blocked as easily as the below. See jbenet/random-ideas#37 for a proposal on how to implement this pretty reasonably on top of regular github issues.

@RichardLitt this may be a super valuable "dev workflow" tool to contribute.
