I have long advocated for making the Ruler a Track. If it were a track it could enjoy all the benefits of playlists. Ruler Playlists would solve many of the wishes I have seen users ask for regarding the ruler. For example, when editing a song, markers become irrelevant to their original intent. With Ruler Playlists, a duplicate of the origin ruler could be made and the newly created Ruler Playlist could be named for, and edited along with, the take. Each Ruler Playlist would contain its own markers and the marker list dialog box would only display the list for the currently displayed Ruler Playlist. The default Ruler Playlist could be made inviolable so it would always be available. I really believe this might be a major improvement for editors.
