I finally released a Go For It! update to version 1.3 for you patient Windows users out there. Even notifications work now!
Unfortunately Glib.Notification does not appear to be supported by Gtk 3.10 on Windows, so I implemented my own notification class, which is not the prettiest of all solutions, but gets the job done.
Feel free to help maintaining the Windows version, as I personally don't use Windows myself. I documented my changes in a separate Windows branch on Github.
I hope you enjoy the changes!
