Your index note is a note (long form note) created in something like blogstack.io or habla.news where it is editable. You populate this with the noteid for the individual nodes you create elsewhere. What I am still getting my head around is how we can automate the process. Say this "event" that I am writing to you can be backlinked to a note if I were to link it here. So, your index note will list all the notes you wrote and basically is a giant list of backlinks
