I'd like to see a "Support" tab added to the new "My Account" dashboard. If I'm not mistaken, as a Pro+ user, the old interface provided me a link to the priority support email address. I rarely have needed it, but when I went looking for it recently, I could not find it.
I think the best implementation for this tab is to make the content dynamic based on the subscription plan the user has. All accounts should have links to the community site for support, Pro users should see an additional link to the standard support email and Pro + users an additional link to the priority support email address.
I would also like to see a link to the change log put on this page as well.
