I was, just now, reading a question. It had a link to some relevant information on another website. I followed the link, which, of course, took me out of the app and into my browser. When I'd read the article, I returned to the app. It would have been nice if the question I was reading were still there. Instead, I was returned to the feed.
Apologies if this is a dupe. This thing times out when I try to search.
