I like the idea. And I do not think Konstantin is shutting down the idea, he is simply pointing out the new flow has not covered some obvious possible errors. I agree with Konstantin that the UI will be (if implemented naively) noticeably slower and there are very little the user can do to actually grok what went wrong if something fails. I'll comment on the wtp-dev thread too. /max /max http://about.me/maxandersen
