Good to know your kindle is working again
The new version is not even a beta release, it just happened that many people found the secret download page ;p
So many of the features are still under development. We will put on an announcement when the first release is out. Actually it will probably be a new thread because we will get a new name. Welcome everyone to join the brainstorming BTW:
