One note in multiple books (unimplemented, see roadmap below)
Let's say you have a "programming" book and also a "python" book.
You want one note to appear in both places, but how?
In order to do so, just specify both books
i.e.
jn "python basics" @python @programming
The above will create the note in "python" and create a symlink to it in
"programming".
The first link is the hard link, the rest are symlinks.
