I believe it is done? I tested a url to a heading anchor in a random note ( https://wiki.dendron.so/notes/f9b4fc21-7613-4c8a-9257-cec4c06b67f9/#onenote ) and loaded it into a private window on Firefox. I see the note's name with a green highlight on the left navigation pane, as well as a green circle indicating the heading on the right navigation pane. Would someone else read the issue and also test it, to make sure?
