I came here to say the same thing. This project is quite old (over 5 years old according to some of the commits). I would expect a little more polish for something that has been around for so long.
It's actually older. I remember using this in 2007 to write lecture notes in LaTeX in collaboration with a friend (our notebooks being connected by Ethernet since the university did not have WiFi back in the days).
The development has really dropped off, and I doubt they're many users out there in the world.
