I started similar topic: viewtopic.php?f=496&t=2504416
(White/black lists for users/topics/subforums OR Advanved Quick links)
My goal is to work in two modes:
* 1. follow only white list - search for new posts of fiends.
* 2. hide topics of foes
* 3. user option to hide specific sub-forums, like Offtopic section or some specialized (like I am not interested in German/French lang but on English only)
The problem is not to hide posts but about efficient notification/update list - I am not interested in foes activity or some subforums at all.
