Powerline is a Vim plugin by Kim Silkeb√¶kken “which allows you to create better-looking, more functional vim statuslines.” Basically, it makes your status line easier to read and look awesome. Installation is pretty simple if you use either Pathogen or Vundler (I prefer Pathogen), but it does require some custom fonts to get the full fanciness effect. Powerline comes with a patcher to patch existing fonts, but there are some pre-patched fonts kindly provided by Nick Quaranto over in a gist, including Menlo.
