Hello. I think that this idea / option would be useful for much people.
The idea is that Obsidian had an icon that produce that be showed the following : a table of content (global for the vault) that is the sum (concatenation) of the table of contents of each note in the vault. The result would can be like the following :

 name_of_note_1
      [Here the table of content (TOC) of name_of_note_1]
 name_of_note_2
      [Here the table of content (TOC) of name_of_note_2]
 name_of_note_3
      [Here the table of content (TOC) of name_of_note_3]
             .
             .
             .
             [AND IN THE SAME WAY BE SHOWED ALL THE NOTES IN THE VAULT.]
