hello +James Miller
Ensure that you send in feedback on what you like or don't like about the new interface, and what you think is missing.
To activate the Feedback Tool type an @ symbol outside of a text entry area, or click on the link at the bottom of the left side menu. https://support.google.com/plus/answer/1678224
Be sure to send in one feedback for each feature you're talking about so that it gets sorted correctly. If you send in feedback about multiple things it may only get recognised for the one thing.
Here is where you can find out more about feedback and see your past feedbackhttp://www.google.com/tools/feedback/intl/en/learnmore.html
Feedback is being actively monitored for users thoughts on the new Google+.
To return to the Classic Interface follow the link at the bottom left of your web browser screen.
