Add outline of headings in the document, in the left pane
Context
Since the named styles on the left will be put into a dropdown menu in the top bar as per #2 (closed), we have the left pane available to have an outline of all headings in the document.
This is nice to have to navigate the document easily.
Proposal
- Add all document headings in the left pane and when clicked they take the user to that position.
- Also show current position by highlighting the heading above where my cursor is. For example if I am in a paragraph, the document outline will highlight the nearest heading above where I am.
Technical implementation
[to be completed]
