Hi, I recently bought affinity photo and designer and I absolutly love those apps.
My mother is recently on the verge of completing her first book from a series that will be published.
During my work on her book we noticed that it would be really helpful if there where preset document sizes of the most common print sizes for example 8,5inch x 5,5inch is a common create space book size and also the book size my mother went for.
Also what would be helpful is to implement industry standard margins and bleeds for those templates so all a user would have to do is open a preset and would have a print ready format with bleed and margins all correct in place.
There are much more of common book sizes and there missing as presets, so please add them in the next update.
