I started with Pagemaker years ago and switched to Quark XPress. I've published three books in Quark XPress and more newsletters and booklets, etc than I can count. I presently have two Website and act as a consultant on two more. I have books published in hard copy, e-pub, and pdf.
What I would like to have is a page layout program that I can teach to other people that do the same sort of things. Right now Quark XPress is way too complicated and InDesign is way too expensive. Mac killed off Pages when they went to the IOS version.
I'll look forward to Affinity Publisher and will participate in the beta version. I have done a lot of beta testing of Mac programs in the past and used to be a certified Mac developer years ago.
