It'd be like coming out with the best To-Do or Markdown editor app for iOS. :)
If I could make a suggestion, at some point you should create an analytics "gizmo" (or whatever you want to call it) gallery similar to http://bl.ocks.org/. You could even just parse the gist examples in Python and convert them to HTML/CSS/JS yourselves.
It would make it much easier to use and understand what can be done with your service. Not that I'm saying you aren't planning something like that. You already seem to encourage a pluggable approach, and what's easier than just going through a gallery and pressing an "install" button. Suddenly, you don't have to know any Python.
