Two related suggestions:
- In the title node, show its index if it is contained in a numbered list
- Allow the “Go to next/previous sibling items” shortcuts to work when the title node is selected, causing the page to navigate to that node rather than just moving the cursor.
How this could work with multiple parents
- If the title node has multiple parents it should have multiple breadcrumbs. Perhaps but the index the node has in that particular list next to the respective breadcrumb.
- If the title node has multiple parents, the “Go to next/previous sibling items” shortcuts could simply not do anything, or it could open a popup asking the user which list find the next/previous sibling in
