[Plugin: PhotoSmash Galleries] Albums?

Hi,

Maybe I am just stupid, but I really cannot find a way to add albums to a gallery. Looking at the back-end, which is really confusing by the way, I just find the ability to control galleries, so does that mean I have to create a different gallery for each album? Also, how can I create nested albums this way? Am I missing something?
