The power widget seems a little buggy on the latest build. I have a button to toggle brightness levels between dim and 100% and I'm noticing that when I hit it the yellow box that surrounds the icon display will come up but it wont highlight the icon and activate. It will usually work the second time I try it, though.
Also noticed some lag here and there with the widget, too.
