Feature request: Show Table of content according to Headers

Hi,
I would like to suggest a new feature to Joplin. I often use many header levels in a note. With a small note, I can easily manage how is it going. But with the bigger one, I hope I can see all the main content of the note based on headers. So, please consider it.
I attached a screenshot from MS Word. I hope you can understand what it is.

Have you tried the TOC for markdown?

Or the Outline Plugin?

Oh. That's great. Thanks for your reply. The Outline plugin looks good for me.
