Hello all maniac note writers 
I'm sorting out my joplin notes
I divided the notes by topic into various notebooks
example
Work (notebook)
study (notebook)
| mathematics (sub notebook)
|informatics (sub notebook)
hobby(notebook)
| books(sub notebook)
what seems to me to be missing is the possibility of having an index note for each notebook, a note that is always positioned at the top of the list of notes in the notebook
I have currently solved it with this type of scheme
Work (notebook)
| index (note)
| Work_note (sub notebook)
study (notebook)
| mathematics (sub notebook)
| | index (note)
| | mathematics_notes (sub sub notebook)
| informatics (sub notebook)
| | index (note)
| | informatics_notes (sub sub notebook)
hobby(notebook)
| books(sub notebook)
| | index (note)
| | books_notes (sub sub notebook)
etc
It's not very elegant
Are there any other solutions apart from calling the note index 0000_index and putting all notes in alphabetical order?
