Just discovered that, on Android, you can swipe back from the forum view back to the list of forums.
That is so awesome. 
So you can swipe back from a Topic to go to the Topic List of a forum, then up again to the list of sites with another swipe-back. 
Read it and weep iOSers 
Swiping to go back/forward also works on the iOS app.
It does?! I tested this and had to fall back to the down chevron on the bottom bar … I’ll check again - did I have an old version of the app?
I should clarify, not to go back to the list of forums. But while you’re in a forum, it navigates that forum’s history, all the way up to the first opened page.
Oh meh, yes, was aware of that … no that’s just very good, but not awesome.
The Android app goes the whole way, and that is awesome… 
appreciate you are working within Apple constraints
That would be horrible. I don’t want to browse history all the way back to forums, specially when I came in from clicking new.
Now I understand why those bot-owners are so jumpy — they never know where they are going and what destination will be 
(I’m using swiping all the time on i-devices)
