For Jim Przywara and others who are interested in having standalone share URLs or PDF tunebooks where the tunes open directly in the Editor when you click the tune title, I figured out an easy solution that wasn't disruptive to the stability of the existing PDF generation in the tool.
The new directive is:
%links_open_in_editor
which can be anywhere in your ABC file.
It also will work with any of the other PDF features like Title Pages, Table of Contents, Index, etc. that you add from the "Inject PDF Tunebook Features" dialog when exporting PDF.
You'll just need to manually enter this directive anywhere in your ABC for it to kick in during PDF export.
Adding %links_open_in_editor will override any play links that might be specified in the PDF features injected at the top using "Inject PDF Tunebook Features".
They can both be present, but %links_open_in_editor will take precedence over %add_all_playback_links.
This video shows two new ways of creating share links, both standalone from the Share dialog and in PDF tunebooks that open in the Editor.
