Just a quickie - but who decided to move from the neutral shades of Green and Red buttons to all buttons, all notifications and all links Purpley-Blue?? I thought my browser CSS was broke when it first happened, but soon sadly realised that this must be "an upgrade" to the style.
Not a fan of the colour choice personally, especially when they clash with some of the remaining green "success" elements. But it's not my platform, so hey ho...! :)
