I have been looking for a simple photo book layout program (Pages doesn't cut it esp. if you need to change something you have done). I understand Affinity Publisher aims to be a comprehensive alternative to In Design etc. It would be great if there were an option in it to have a "Personna" or something which would allow someone who wants more capability than Pages but doesn't want to deal with "too many" options to be able to master the basic layout features. I have somewhat mastered Photoshop, no desire to repeat that experience. Something along the lines of a "Lite" or "Elements" option- doesn't need to be a separate program, just a way to work with a stripped down feature set.
And, I would hope, a way to deal with an output format which would satisfy photo book publishers In Design format (or is there a PDF format output option?).
