As a past PagePlus/PhotoPlus user I find the missing save, undo, redo, print etc. toolbar icons the most annoying "feature" of the Affinity products. The only thing that is more annoying is that I cannot directly import PagePlus files into Affinity Publisher and have to do this through a PDf file, which loses all the formatting for mutli-page documents and any master pages I had set up.
I bought Affinity Publisher when it was finally released, but I find myself still using PagePlus. As a PP user since version 2, the differences between the two programs are too much for me to pick up Publisher when I have something to do quickly. I have just needed to update my labels for the choir I am in and found that exporting from PP to Publisher via a PDF does not preserve the fact that there was a master page, nor does it allow me to print multiple labels to a page without some serious time being spent on reformatting the document. I feel that Serif has let its user down very badly with the lack of either a direct import process or a separate conversion program to convert PPP files to Publisher. I will still use PP until Serif gets their act together. I was planning to buy Publisher for Windows so I could work on either my Mac or PC, but at the moment Publisher is just not up to scratch for me. As a very long term customer, I am very disappointed and can see me looking at other packages if things do not improve soon, although I would loathe doing that as I have many years of PPP files that I still use as templates for new documents.
