I'm an RPG book publisher and I'm pretty excited about the release of the new designer tool. Monthly fees for software got me down. Anyway, our next book will be in our Dwarven Epics line called "Delverr's Cave" and I'm going to layout the entire book in Affinity Designer. Check out our progress at www.DwarvenEpics.com
Also am using it for our newsletters in our monthly subscription crate for www.DwarvenCrate.com
Keep up the great work!
