Thank you for the kind words Brian - while I agree with you on autodetect relationships being a major problem, probably the thing I like the least on PowerBI is actually the auto date feature. This causes SO many problems for newbie users, I wish they had never included it in the program.
After that I would probably rank autodetect relationships, and detect column type behind that.
Quick Measures, while very annoying, are one of those things that I can just ignore - although I’ve had to caution more than one new user about the possible bloat in those measures.
