There's a multi-party problem that's arisen. Unread Books Glow author is indicating (elsewhere) that he's having problems with the latest CK updating for DLC. SkyUI could use an indicator that a book has been read for sorting purposes. USKP keeps track of quest books by recording whether the quest has been started. AFAICT, everybody is doing it differently.

These three mods are all well done, and absolutely essential. If we could bring these minds together somewhere, I'm sure they could all be compatible. So, I've started this thread. (I'm only a selfishly interested bystander.)
