I wanted to follow up on this.

I have a semi-working version of this for windows on my branch here.

Currently it only supports git bash on windows. I've tried to mess around with powershell and frankly it just sucks, I don't really want to anymore (lol). I'm not sure if you'd want to add this in it's current state, but what i've done allows quicknav to work for my use case which is git bash on windows.
