I think it would be a good idea to be able to filter the "Show unread posts since last visit," as I get somewhat annoyed when I click to see some recent topics and see all this stuff from the altcoin section, which I have no interest in. We should be able to block topics from a certain section from coming up in our "unread posts since last visit."
this feature would be very useful. +1 for coming up with it.
it is true that most of the time the "unread posts since last visit" is flooded by altcoin topics and (more importantly and annoyingly) local topics.
