I agree with you that irix-style thumpwheel is not the best solution. I
don't like that is has a fixed size. And the design has too much
character, it might not go well with every theme (and how should the
theme engines really draw it?).

Finally I have installed gnumexp. And, yes, that was very similar to
what I have in mind. But since it's function is to replace the
scrollbar, I think it's slightly too different from the scrollbar. And
the feature of scaling without keeping the aspect ratio I believe is
more of a misfeature outside the mathematical field of application. I
guess a separate zoom function is is the better in most cases. I'll ask
the usability people and see what they think.

Applications such as Dia was also what I had in mind. I made a mockup of
how I imagined that the widget could look like (in applications such as
Dia). I hope nobody minds that I post pictures to the list?
