I am always interested in feature requests, and this is exactly the
right
place to put them.
And you're right; that is a feature that my app should have, and I am
thinking about the best way to implement it. One challenge is that a
single photo is often contained within multiple groups (i.e., the
owner's
photostream, groups that it has been added to, possibly your
favorites,
etc.), so I want to give the user the option to choose which of those
groups to move through if they swipe or hit a "next"/"previous"
button.
But I think I'll figure it out soon. Thanks for the interest.
