My vim and tmux configs, using airline (as discussed [here](http://www.rousette.org.uk/blog/archives/tinkering-with-vim/). The Powerline theme is pretty much the default (may be a bit old now) and I just commented out a few plugins I didn't need. I use the patched Sauce Code Pro for my powerline/airline font.
