I did "pull request" from my fork, see here:
https://github.com/yifanlu/KindleLauncher/pull/1
If you're interested in my fork see
https://github.com/JustAMan/KindleLauncher
But you'll have to compile it yourself and install yourself, too. I won't step in Yifan's way - it's his Launcher, so I'm not distributing my fork in update.bin.
