I've it always opened in a pinned tab in Firefox. When coming back, I see a message like "You've XX new tweets". Now, if that number exceeds e.g. 10 it's hard to remember exactly when it started filling in new tweets.
I.e. I see no visual indication that "from here on I just loaded new tweets for you".
I'm having trouble "keeping up" to not miss any tweets because it's just tough to remember every time where I exactly was.
Is there any help for that?
