Hi,
Currently there are no control elements. This is planned for the next version. I’ll try to speed up development on this aspect 🙂
Allowing rotation only on certain pages is an interesting idea. I’d have to work on that.
At present, your only option is to limit the Auto-gallery setting to certain sections with the “Galleries per Section” setting. By default Section(s) is set to “article, div.hentry” which works on most themes and will include all images inside one post or page. But you could change it to “.gallery” to only allow rotation on WordPress galleries.
