Idk what client you're using, I'm using connect. But I was told that if you hit the 3 lines on the top left and select front page it should be exactly that?

I don't really like the way it's organized though. And I wasn't subscribed to enough communities when I posted this to actually populate it adequately... It might be better now that I've got the "hide read posts" and "scrolling past posts marks as read" options on. But I've still been looking at all and trying to find communities when I think of them
