one question. I recall from reading earlier posts that filepicker.io backend is built primiarly on Flask framework. Are you including library for Flask as well ?
We were looking at flask, but weren't sure the best way to make it a "library" - most of the basic functionality can be done via the requests library, for example.
With Rails, Django, etc. we were able to build into the ORMs and templating engine in a way that made for some cool magic.
