Agreed. It would seem that the devs have a habit of thinking everyone understands this system as well as they do. That isn't a slam, I think it is valid criticism and something that all of us are guilty of. Doctors are notorious for using jargon and talking over the heads of patients and this is something I know from first hand experience and takes constant concerted effort to improve.
Anyway, you make good points. We are in beta and I can only assume that the UI will get a dedicated team to deal with making it more new user friendly. If we are to get many new users here, and keep them, this will surely need to be addressed.
