Thanks a lot for your input. That was very useful.

So would you say that it makes more sense to spend time improving the
TIFF save plug-in or would it be a better idea to invest that
development into a powerful PDF export? My experience with TIFF is that
it is an extremely difficult format as most of the important features
are implemented as some sort of extension that is not part of the TIFF
6.0 specification. I would hope PDF to be better specified.
