Favorites and number of topics per page

Dear habrararedktsiya, not so long ago I found in my favorite inscription "(habratopik inaccessible to you)." It is logical to assume that the author of this topic has closed it from viewing, but why is the opportunity to remove it from favorites as well? Please make the “remove from favorites” button work independent of the topic's visibility.

Now on one page fits 8 habratopikov, please make this number customizable.
