Thanks for the thorough reply.
foo_navigator does mostly what I had in mind - pity it's no longer updated for current architectures.

Hi

@name "Playback History"
When pasted on JSPanel 3, it is only white.
Are there any other settings required?

Hi!  After adding the script to the new JSP3 panel via Configure, it will remain "white" when you tab to it because there is no GUI, all the script does is write the text file with the name specified in the script to the location specified in the script, the contents being the playback history entries.  It acts as a replacement for foo_nowplaying2, and though you could use both at the same time the text file names must differ.  At the time I added it, there was no 64-bit replacement for foo _np_simple 1.9.1, and I wanted the same ability with 64-bit v2.

The comment I made about adding JSP3 Text Reader setup to display the contents of either log file from the above was "conceptual"--I haven't tried it but it seems from the sample description on the JSP3 site it could be done.  I prefer just scanning the text file in Notepad if I am trying to recall a particular song that was played.
