Yes the anchor selection window needs some more work to be really 
useable. However, I mainly use vertical and horizontal control points to
level my panos.

Workaround: deselect the "auto" button on the preview panel.

Hard question. you probably have to guess. However for architectural 
panos it is much better to use vertical/horizontal control points. Bruno 
has written two great tutorials (on the hugin website) about their usage.

Hmm, I could not reproduce this behaviour. When does it happen and what 
are the consequences?

Well, the current preview window is just a preview, not the final thing. 
  I'd like to have a fast zoom feature as well, but I don't have time to 
program it.

Select Nona, TIFF output and tick the enblend button. You do not need 
any additional command line arguments. Well -v is recommended it you 
want to see enblend's progress.

You can do this by adding 90 degrees to the roll angle of the anchor 
image. Reoptimize, Stitch and rotate the output image in GIMP or so.
