Not only that, but it would be much nicer if instead of just rotating there
was a way for the text to follow the path of the polyline. There are also
problems on choosing the point of the polyline to calculate the rotation
angle. For example:

Some St
--\
   \
    \
     \
      \
       \
        \

As opposed to

--\S
   \o
    \m
     \e
      \
       \S
        \t

Hi Carsten.
 1. As far as the decluttering, I was going to leave that to the
OMLabler/OMTextLabler.
    I looked at the link and the NLPF stuff.
   From your posting i didn't get wether that got integrated.
 2. I did some experiments with the rotation angle, it slows the drawing of
the objects to a crawl.
 This is partially due to the Shape layer/plugin don't filter out all the
things that are not in the projection(unless I missed something).
 So, quite a few issues to work out.
   Thanks for the input.
    JR
