An option to hide, remove or move the overview box from within albums would be great. As it sits right now it takes up one whole column of a album and the primary focus of an album, the pictures are being squished into a 2-row. Adding a sidebar to this makes it even worse. Categories look just fine, albums do not.

Whoever though that a single overview box should be put where it is now should think again.

Agreed. I modified the template to achieve this.
