PagePlus X9 turns out to have sufficient functionality in layout design to replace InDesign CS3. (See the prior post “Migration” for why I have to change).
PagePlus is a product of Serif, a long-time competitor to Adobe. The Plus line of software is no longer in active development but licenses are still available – PagePlus is $25 from Serif directly, or a bit less in DVD form on Amazon.
Down the road a bit, the company expects to have a more full-featured layout package (Affinity Publisher)… but it’s been pushed back several times. I think the main development effort is in their Photoshop replacement software.
As to PagePlus, so far it’s worked fine for the four-to-eight page layouts I routinely need; shortly I’ll test it on a longer project.
