Outline Sidebar in Mobile Apps

I think it would be a useful feature to have an Outline Function similar to the Desktop Outline Plugin (https://github.com/cqroot/joplin-outline) but on the Mobile Apps. For example, when you click on the 3 dots in a note you can select "Outline" as an additional menu item. Then it would list all "Headings" in the document allowing you to jump to the desired heading in the editor. It would make using a larger document on mobile much more feasible and functional. It would be nice if it could work in both "Markdown" mode and "Reader" mode too.

Not sure how technically difficult it would be to implement and not sure if others would find it useful but I'd be interested to hear feedback from the community.

Thanks for this awesome app.
