Comment 11 for bug 1567685

I agree it's not easily discoverable but once you know it, you can swipe (for example) through articles in news scope or results in the Ubuntu Store scope without going back to summary. For me it's the same as swiping through photos in Gallery app.

Maybe it'd be better to make it more discoverable for potential new users than removing this functionality from the users who already use it and like it very much.
