Love your gallery customization, and I'm very happy some people are experimenting a little with the theme settings! There is a lot of unexplored territory ...
I especially like the large thumbnails, the simplified thumbnailscroller and your twist on the main menu(with autoclose).
You should look into the new update released today(21. July) to increase the speed of your gallery load -
