Actually, this works! Thanks
I was trying to divide every project into its own notebook, and wanted to have a "Project File" at the top.
Instead, I came up with this workflow:
create a Project Files notebook
create a "project file" with the name "#<Project Name>"
move that file to Project Files
add it to shortcuts
Then I have a list of all my project files under shortcuts.
The secondary benefit is now my notebook for "#<Project Name>" won't be cluttered with project files: mine contains only actionable items. (I'm doing a GTD type thing)
