I love the negativity in many of the responses here. Obviously people like native apps. Macvim is a thing. Emacs has a gui version for os x. Sublime is a thing. This is a polished port of macvim that has a file drawer, which is a feature that many people want baked into macvim. Browsing complex file hierarchies and large projects isn't great inside a terminal, and is a giant hurdle for many new users of vim.

If this isn't for you then fine but don't rush here to proudly proclaim how you don't understand the point of this. I don't know why anyone submits their pet projects here.
