Hi

That’s the Favourites at the bottom of the screen under the comment box I think you’re referring to, I’m referring to the list that appears right at the top of the screen. It seems to be mostly filled with random magazines but on the left hand side are four items that seem to be groups of magazines;

So you have All, Subscribed, Moderated and Favourites, assuming Favourites should work like the others (ie a group of magazines related by the heading title) then I assume Favourites would be a self built group of Magazines that you want to see with one click.
