I am a new user to Affinity and I have the iOS version on my iPad Pro. I am following along with the tutorials and I have 3 suggestions that will help me, and might help others as well.
1. The iPad in the tutorial is diagonal to the screen I am viewing and it is difficult to see what buttons he is pressing.
2. The pictures he is using in his examples, I do not have any of. Perhaps, in the future, you could include those pictures as downloads, so, as he is making adjustments, we could as well. This would help me remember what buttons are where and would enrich the learning experience.
3. Have the tutor slow down in his selections. His tempo is fast.
