The display of "remote" games is useless
Migrate from https://bugzilla.gnome.org/show_bug.cgi?id=778907
Games which are not integrated into Games display a message stating to use the game's own window.
This is barely useful, it would probably be better to not have this page at all or to use it to display information about the game, similarly to this mockup for Videos: https://raw.githubusercontent.com/gnome-design-team/gnome-mockups/master/videos/wireframes/series.png
What about hiding it (going back to collections) as soon as the game quits?
That's what was initially done but it didn't work well: some commands — like the one to run Steam — where spawning another process doing the real work and were closing quickly. For consistency's sake this feature have been removed.
And anyway that wouldn't make this screen less useless, just less noticeable. :)
