Toggle between the images of only one gallery

Hi,
I installed your plugin as an upgrade from lightbox that works better with mobile devices and it works but I cannot find any settings in the WP menu, except for the js and css files of the plugin. Have you included a menu or are all settings to be modified in the edit section of the plugins menu?
1) How can I change the transitions?
2) How can I set up Fancybox2 to display the images of only one gallery?
I have multiple posts, each one has a thumbnail image activating fancybox with rel=”lightbox[galleryname]” and several more images connected in that same [galleryname] in the same post. As a default setting fancybox2 displays all the images on the site as a continuous gallery, and I cannot find how to “uncheck” that option.
Please, help!
Thank you!
