One other minor nit: I think the usage video on github is way fast, I can't read what's being done and takes a few replays to understand what's going on, plus all that fast movement is actually distracting (a bit headache inducing even) and may drive people away from reading down the readme. I'd go for something at least three times slower. Well that's how I felt, at least. But really great plugin, have you looked into vim-fugitive? There might be opportunities for interplay between the two plugins (e.g. fugitive allows navigating to commit objects with :G[edit|split|vsplit].)
