Packaging the document assets (images and fonts) is almost a necessity for printing services, especially the fonts. Though it is possible to do this manually, coming from InDesign, a mouse click is really nice. Not to say this would make or break Affinity Publisher because I will use it out of beta regardless. As it appears, Affinity Publisher will soon become an industry standard as viable as InDesign. As a graphic designer and pre-press manager for 30+ years, I have dumped PS and AI for Affinity Photo and Designer because of the direction and pricing Adobe has decided to go. Despite the slight learning curve, I have never regretted it. I know of many designers and photographers jumping on the Affinity bandwagon and waiting for Affinity Publisher to come to fruition and become free of Adobe. Whereas a "Packaging/Collect for Output" feature may not be a deal breaker (for me), it will go a long way for the future of the software considering that hopefully Affinity Publisher will be as long lived and productive as anything Adobe has produced (provided it stays in the right hands).
