I use the "Playlist" function in the web admin, under "Files & Media" across the top of the admin page. I have several playlists set up, and although this will get you going, the ability to have an "Add to Playlist" while choosing the file in the UI would be terribly groovy, at least this will give you a starting point. I use this for audio files, tv series, and movie marathons

.
Hope that helps,

Yep that works well too... but from a users perspective they expect to be able to dynamically add to or extend a playlist while they are listening to it. After all every other media player out there does this... its just one of those standard features people have come to expect now.
So this one definitely needs to get 'fixed'. The problem is that the code in question is deep inside the Orbiter and it is a 'non-trivial' change from an engineering perspective to make. We'd be willing to help with this by committing some engineering time. I'll post something in the Developer area in the next day or so and see if anyone is willing to help out with this.
All the best
