It's important to remember that UNA modules are not always complimentary. Many of them overlap in functionality and sometimes should not be used side by side at all. For example, Albums, Photos and Videos - you only use Albums for Facebook-style erosional mixed-media albums, while Photos are more for sites like Instagram, and Videos are for sites like Youtube. Albums contain photos and video files, but grouped, so they can't be browsed as a separate media types. It owed be way too confusing to use all 3 on ones site, especially if there's no clearly articulated purpose difference for each.
