Here's what i would like to see in next releases or patches or templates.
 - Ability to make lightbox with gallery group (something like rel="lightbox[$galleryid]). Also include ability to open lightbox in gallery view (like in superclean template, but you wouldn't need to close and open lightboxall the time) and use next and previous buttons in this lightbox to look through gallery.
 - And the other feature is thumbnails instead of navigation bar in  "Mian image". I mean put images instead of this: " <<first <<previous numbers nest>> last>> " And somehow highlight current image in this strip. The way it could look like: http://mmorpg.com/gamelist.cfm/game/267/view/screens/display/12526
