I don’t know if this is welcomed or helpful, but I figured I would try to contribute by pointing out a feeling I have as I’m working through the beta.
Beta doesn’t build on itself and allow me to really see how adding an element or property changes the webpage. It may just be me, but I find that when I see things building on each other it helps synthesize the knowledge. I also really like non-beta’s real time preview for this reason; the real time preview is a feature I find myself missing in beta.
It also feels cluttered as I move through the lessons, but that may just be a symptom of things not building on each other.
I don’t know what I can do to help, but I’m willing to help any way I can - even if I’m just a know-nothing rookie .
