From all the gallery scripts I have messed around with these seems to be easiest to use and setup. I was wondering if for a future version you were planning to add page number feature for albums. This I think would be better for larger albums so the user doesn't have just a more thumbnails button as this can get a bit tiring.
Although I can manually tweak the code a bit to get a fairly reasonable page number setup, it would be nice to have it as a feature.
Good job on this plugin as well!
