No. These are exactly the probles I have found.

I would not like this solution either... But if there is no other
means, I think this is better than not supporting the possibility
of "backward step" actions...

Sorry, I did not know these technical details... I think the
problem of not-very-good visual appearance of pdf-converted
images can be solved somehow. The larger size of pdf versions
seems more difficult to me.
Thanks again for your contributions!
