Topic: navigation arrows left and right of the thumbnails ?

it would be perfect if the navigation arrows can also be placed left and right of the thumbnails instead being always below them. i think it will help to bring the layout in a better shape when using the thumbnails at the top or bottom of the image.

there is also a problem with the navigation arrows when i display the thumbnails left or right of the image with only 1 column. then the 2 arrows are overlapping each other.
