I've been playing around with a 3.0 photo page, I need an option like Listings from App.io and I think quite possibly this will work beautifully.  I know there are a few of us that were concerned about losing the Listings  and this is one of my top priorities for the changeover of my site.  Has anyone else tried out the new photos?  The other thing I noticed is that a picture can have additional pictures..lol  ~ Haven't figured that out yet, but it's almost like different views...as a listing may have.  Will be building this concept on my sandbox and will update as I move forward.  If anyone else is working on this concept, would love to connect to build this idea ~
