I'm not sure if anybody has noticed, but I did while looking around my collection that the header is overlapping. Not sure exactly how to describe it, so below is a screenshot of what I'm referring to.
It's far more noticeable when you go to the "About" page.
It seems that the icons on the far right (highlighted on the first image) are the culprit of why this is happening. Maybe if the're better organized this could be fixed.
