Number of Playlist or Timeline Media Items

The number next to the playlist or timeline name in the playlist tree and playlist/timeline contents header corresponds to the number of media items currently contained in the playlist or used in the timeline composition.

Locking and Unlocking Playlists and Timelines

A playlist/timeline can be locked to prevent accidental modification. Locking and unlocking of a specific playlist/timeline are toggled by clicking the padlock icon next to a playlist name.
