I got say that my first reaction to having a in-app browser for a Discourse instance was: meh, Safari could handle it better. But now I’m kinda liking it, it is a quick way to look for help and/or read the news about Agenda.
One thing needs to change though: the Back / Forward button are on the wrong side of the window. Also supporting gesture base Back like in Safari would be nice.
Or it should just open Safari 
- there an back again.
