Adobe PageMaker
Or you could try to talk Adobe into putting out PageMaker for Linux, not
that they have a great track record of bothering to do this. :) Another
option would be to help the Scribus project improve the efficiency of their
file handling. This is probably where I would start. I don't know how aware
they are of the problem so you could start there, and if you're not a coder
at all you can offer to help do detailed testing so they can narrow down
the problems.
