Make it readable and return the ability to mark emails as read without having to select them.
Increase font size as default and return the ability to mark emails as read without having to select them. The new is illegible in it's default as the font is too small. I shouldn't have to adjust the font size by holding ctrl + using the mouse scroll wheel. I should be able to quickly mark email as read. It's currently too many button presses. You switch to the new email is an unmitigated disaster. Why on earth would you reduce functionality and make it harder to read? Is your goal to push your few remaining customers to gmail? I think you may just succeed!
