I'm wondering if the Pro version is worth the extra money, but so far I haven't found more specific information about it.

At the Overview page it says: "The professional version of PageStream includes a number of add ons that were sold seperately as well as advanced typographic and graphics capabilities.", but is there a list of these add-ons somewhere and do they work with the MorphOS version of the program? And do these advanced capablities affect on MorphOS?
