Wow, since 2013 this has been asked for and never delivered. Shows why management needed changing, but the question is will the corporate culture change and become responsive to users -- the real ones who make the company go as opposed to investors. I won't become a premium user again until I see real change (I left in July 2016 because of the lack of responsiveness and feature changes customers wanted, but leadership who still wanted to drastically increase the price -- I am willing to pay for value, but can't see the value equation, yet).
Time will tell. I'd say it has to be within 6 months from now.
