Yes! This is a win. At least from my perspective, anyway. Was very frustrating to have to remember to go to Dashboard --> Appearance --> Widgets to get to the Widget admin instead of just clicking on the Widgets drop down.

I get that the customizer is where WordPress is going. But I still don't like using it personally. But then I still nearly exclusively use the text editor for publishing instead of the visual editor too. So I know I'm no where near the center of the user bell curve. Heh.
