One Shortcode that will list the names of all the gallerys??

Actually, for now it’s possible to configure it manually. For example You can create root gallery which will work as preview – front gallery where every image of the gallery will be linked to the other pages or posts with child galleries.
Every image of the gallery have link field where you can define custom link for every picture.
In close future we have plans to add much more interesting functionality and albums is one of this feature. Please watch for gallery updates.
