As a reader sometimes I feel permalink icon beside the subheadings in the wiki pages will be helpful.
- When the user scroll mouse over the subheading of the wikipage permalink icon should be visible left to the subheading.
- When the user moves the mouse away to the subheading the permalink icon should disappear.
- When the user clicks on the permalink icon the page should be tagged to that subheading something like /wiki/wikipage#subheading
I hope this is clear, If not I can provide some more information/examples for inspiration.
