In general, I think the GitHub issues page is a good place to raise a feature request if the request is well-scoped. If there's more uncertainty about the feature and how it might evolve, I think it's worth raising in the community forums first just so a bit of preliminary discussion can happen first.
We've been hard at work trying to prepare for the v1.2 release and so have been focusing primarily on high-priority bug fixes, but I'm hoping we'll be able to allocate some more time for feature work with v1.3.
