Upcoming UI changes for UNR

[Loïc Minier]

        Hey folks

 We're pondering the addition of gnome-web-photo to the UNR seed; this
 would change the appearance of the web favorites in UNR: it would add
 screenshots of the website added as favorites.

 I wanted to give the doc team a heads up on this in case they started
 doing UNR screenshots already.

 Discussion about inclusion is in 425464; MIR bug is in 427833.

   Thanks!
