@gazumped You're right, and I accept the workaround solution.
But, is there a way we focus on writing notes that contains H1, H2, H3, etc., headings, and Evernote magically picks these headings and creates a table-of-contents(TOC) that displays on the right of the notes? Now, students can click the headings on the right sidebar, and it directly takes the student's cursor to the clicked heading of the written notes in the same single note.
This is a feature request I suggest.
