1. Savii Albums, like the categorization that 3D Photos use(?), where you can group any Saviis (even those that you don't own) into a page that would act as a story character list or favorites.
2. Savii BBCode, which would function like figure tags. You could type "savii 1" in brackets to show an image of the Savii with the ID of 1, and clicking/tapping the image would bring you to its profile. This would/could replace having a single Savii on a profile or blog, too.
