Not on its own, it is locked to the main window, however you can move the timeline to a separate screen, move the other panes around and add panes as shown below - timeline is on left screen the rest on the right.
Note - I have added the peak meter etc and Mixer panes on the right these can also be moved to the left screen as well
Note: the mixer pane will not reappear when you restart the program, however pressing the M key, it will reappear where it was last placed.
