Could you add/did you add killing the annoying "call to action" pop-up dialog? You know, you visit an article and BAM! A fullscreen modal asking to sign-up for their book newsletter? That would be awesome.
Even sometimes I don't pay much attention to it and when after reading other tabs I come back to this tab; all I see is that pop-up standing there, asking for attention. It even makes me forget why I even opened this tab in the first place and makes me leave immediately.
