Hi Paul - I'm not sure I like the coloring on the left with white text when selected, and there are some formatting issues (at least on my screen). For instance on the Email section, the fields appear below the left menu. Otherwise the look seems good. I'll also say that when accessing this profile screen from the Gmail gadget, its a little confusing... At first, I didn't know what the password, notifications, and email sections were referring to. I started thinking that the Gmail gadget may have a separate password, and that the Gmail gadget may be able to email reminders and SMS alerts. Its only when you mentioned that this is the new My Profile screen that I realized that this was not a settings screen only for the Gmail gadget, it was the my Profile screen.
The new My Profile screen will work well from within Method, but I'd suggest hiding the left menu when clicking on settings from the Gmail gadget and only showing the options under the Gmail Gadget menu item on screen. See what other feedback you get, but I think many users will be confused by that at first.
