@Ken: I did it again with the 1-step hack. KOreader works like i told above.
The Louncher is nice (expect the license / registration!), don't know it until now.
Let me say that i like the work you do. For me its a step in the right direction to more open ereader and better software (every of the aktual ereader i know have some issues i realy dont like) and i hope you don't stop working on it (or help me, if there is a problem with my installation procedure
).
