vim is nice, but I'm still struggling to get 100% auto-completion (I'm using jedi-vim and sometimes it doesn't find stuff I'd expect it to) and I have no refactoring ("extract method", "change definition", etc.) or "go to definition". Can you recommend me how to configure it for Python editing? I've tried many guides, the one I used is http://redkrieg.com/2012/12/11/writing-python-like-a-jedi/ but it still lacks a lot of things... Thank you very much!
