Reading one post at a time

On a phone, the icon at the left end of the header switches the feed into a one-post-per-screen view. Swipe up and down to move between posts. In this view: double-tap the picture to like it (double-tap again to unlike). A single tap deliberately does nothing, so a double-tap never opens something by accident. The title, the author and the first lines of the description sit under the picture — tap More to read the whole text, Less to close it. The buttons on the right are like, comments, save and share; the author's face above them opens their profile, and the + on it follows them. The same icon switches back to the grid.
