This plug-in allows custom separators to be inserted into your playlist to split sections or to add in stopping points when reached along with a plethora of other options. As can be seen from the screenshots of the playlist editor menu options (to the right) and the preferences page (bottom of the page), it is possible to create a number of separator presets as well as being able to highlight the separators so they stand out (see the notes). The Winamp forum thread related to this plug-in can be found here. | | 
This shows the separator options available on the playlist editor right-click menu. |
