Statically check your Python code for errors

I would consider using import * as an error per se, and other improvements over pyflakes seems not worth switching. Question: does it have a vim plugin, as pyflakes have? Displaying errors in the editor is helpful.

This adds some useful features, but why would you need a fork for this? Seems more useful to merge it into pyflakes than to pretend you've made a whole new tool.

Please fix your social badges. Unless I'm maximized horizontally (almost never), they obscure the post. Linux, recent Firefox.

Try PyCharm, this IDE has built-in static code analyzing feature ("inspections").
