I just installed Beta 5 and am just getting into it. The first snag I hit was that it's forcing me to upload a course image and also to fill in the meta fields. Do they really need to be required? For now I'll just slap something bogus in there, but I think the meta fields shouldn't be required, and I'd suggest that if the admin doesn't upload an image, it would default to a stock image built into Shika.
I'm looking forward to digging into this though!
