"Fullscreen vergessen" würde ich nicht sagen, auf der letzten Seite deines verlinkten Threads steht aber, dass es (noch) nicht geht:
Originally posted by FastIkarus: I guess "full fullscreen" cannot be easily done now, but would be possible to make black areas responding to touches? I really like touchpad control mode and if it would work over whole display, it would be wonderful.
That could work great! It will seriously mess up the coordinates handling and non-touchpad mode... but hmm, I'll see if it can be done. And unfortunately full stretched fullscreen will have to wait for now.
