You can make playlist separated windowor, vice versa, docks it to Main window.
How to do it:
Playlist can act as desktop tool bar. To do this:
When program becomes inactive, playlist hides. To show playlist you need to move cursor to the screen border – marker appears. Click on it to return playlist on the screen.


Note: On the moving files into playlist via Drag and Drop it's not necessary to pull playlist out – move cursor to the marker and playlist window will appear automatically.
