As Cia mentions, Reading Lists, which will be a feature in our next major update, will handle all the favorites. Favorite Authors, Favorite Stories, and you'll be able to create lists of people or stories. For example, you could create a list of "My Favorite Readers".
The dropping of the old listings at this time was accidental. But it actually plays exactly into what the problem was. Favorite Stories and Favorite Authors was based on "liking" a story. When we changed to reactions, that disappeared. It was something we missed because we've been working on the replacement. I'll check with the programmer... if it doesn't take much effort, I'll bring back the current system. If it does, we'll have to wait until the replacement. Sorry we missed this.
