The new (updated and hopefully stable) distribution of files is located at the bottom of this post.
New in this release:
1) Per recent changes to YouTube's site front end, I fixed the script's ability to determine a given video's title.
The paid-for version of the app is not affected by YouTube's recent changes.
The full version of the software will continue to function as before -- perfectly!!
As always, please let me know if you have any questions/concerns regarding the above and/or the code.
