As it turned out, the initial UI objective was noble (saving time), but in the end was too complex for most users. There is a quote about this:

Nice post, Paulo! Yet another reason why usability tests are so important.

I often read Baymard Institute's newsletters, which present simple heuristics on best usability approaches - definitely worth the 3min reading!
Thanks for posting, very interesting post! :)
