Use this specialized-autocomplete-enabled text box to construct a program. Just write songs, speeches or activities with their file/directory names and sections with a single leading # sign. You can include notes about speeches (e.g. which litany of tarksi) with a colon, a tagline for the whole thing with curly braces, or autoslide-only audio links with parentheses after a song name.
Optionally, start from an existing program:
When you're done, c+p this into a new .list file in the lists directory. You can use Github's GUI for this if you like.
Or create an of your program, complete with audio to sing along to, for use in smaller solstices. Note that list slide show is not saved everywhere, so you should probably c+p the program somewhere safe first.
