[BetterRed]

@Tanjamuse

One way would be to use Alter Tag Browser->Manage Authors tags etc->Manager User Categories to create a User Category called Favourite Authors, set Category Filter to Authors then select Authors from Available items list and 'move' them to Applied items list.

Then create a new Virtual Library (Favourite Authors) with search expression @Favourite Authors:true The @ indicates its a User Category search.

There may be better ways, but that's how I create arbitrary sets of Authors, Tags etc.
