Unclaimed tasks for developers
It would be useful to have an easy to find section detailing unclaimed tasks and the requisite internal and external documentation it's anticipated will be needed to complete these. This way developers unfamiliar with the project can quickly get to grips with what's needed, what the specifications are, and can create and push contributions with the minimum of fuss and the greatest confidence that (assuming solid coding skills) their contributions will be accepted and their efforts will be fruitful/helpful to the project.
