I did a search and couldn't find any results (probably from my terrible searching queries). When I open a site on my desktop to wikipedia, for example, it displays the desktop page. If I then open Orion on my mobile later, the page is changed to a mobile site. If I then go back to my desktop, the page uses the mobile site on my desktop.
It would be nice to see the URL changed to use a desktop site on desktop and a mobile site on mobile when switching between them, when both devices are synced.
