This is presently my favorite theme in the IPS marketplace. It's clean, flat and easy to navigate.
I love themes that offer custom header backgrounds with overlays as this one does - they let you easily give your site a unique quality with minimal effort.
Everything else is easily configurable in the theme settings.
As a general rule of thumb, if you are not using a boxed layout, I would strongly recommend disabling the page background setting. I have found that this setting alone has a significant impact on page performance (to the point it causes significant scroll lag on my Surface Book), even though it is normally not visible unless you are using a boxed layout.
But overall, an excellent and super clean theme at a very good value - these are the types we need more of here.
