Both of the first bugs you pointed out have been fixed in the final version and I will be updating the repository to reflect this soon. I really need to spend some time packing up the final version so may not bee untill sunday I'm afraid.
If I understood the repository-thing correctly, than I do not need to make a complete new persistance usb, I can update then over internet, right?
Thank you for your help. I tried to setup ssh_x11, but during the connect from windows, putty is prompting me for a password, which I do not know...

Is there a standard-password?
