The * marker is used / shown on Series. Would be handy if the * marker could be shown inside a given playlist.

Interesting idea, but not certain it's feasible without a significant change to the database. The series titles are all contained and tracked within the DB, while the playlist is an external file. For your idea I believe it would be necessary to store the entire playlist contents within the DB. Certainly possible, but can't say if it's feasible. Zip would have to weigh in here.
