It's non obvious how to find the Forve vs Cadence and Histogram graphs. If I didn't remember them from the splash screen I would have gone looking for them. Their text looks disabled.
I agree. The UI is very pretty, but some text is clickable and some isn't, and it isn't always apparent which is which.
Also, the intro message after signup is a fantastic idea, as is using question mark footnotes, but again, I didn't notice them until I read the message.
