Nope, don't like it. The built-in git commit log is plain but space-efficient, displaying all you need in a small number of columns. If you want a commit graph you can get it just fine with git log --graph.

Short, this doesn't seem to to do anything you can't do with plain git already and what it does is not as good as what git does by default.

Edit: apologies to the project maintainer btw, but I really don't see the point.
