In the main window, View/Customize Interface popup add new subsection similar to the following:
Playlist [ ] Show Current Playlist Path in Titlebar (after filename)
............[ ] Hover over toolbar playlist icon shows up to 5 lines of playlist
5 is user changeable default. Lines shown are 2 previous + current + 2 next or more generally,
....lines_shown\2 previous + current + lines_shown\2 next, if lines_shown is odd , or
....lines_shown/2-1 previous + current + lines_shown/2 next, if lines_shown is even.
For me this would make unnecessary probabably 95% of times I now have to (a) have the Playlist open and (b) switch back and forth to it.
Best wishes,
