Love this idea!
I was about to make this request and gladly found this.
Although I am not yet quite sure how helpful my new practice of keeping a note with the entire hierarchy of my vault will be, I do know that if I could link to folders, things would be a lot easier to maintain.
I have a vault Tree of Content note that simply contains a hierarchical list of my vault. It is a little bit of work, but it keeps me honest and deliberate. One thing that I struggle with is that for folders, a name change is not reflected in my Tree of Content. And since it is re alphabetically sorted within explorer, sometimes it could be temporarily lost and not easily found.
In terms of creating these folder links, perhaps with the action of dragging a folder into a note, they would be created.
Below is a side note that I wanted to mention because of its relevance to my use case (will gladly edit out as I definitely am not intending to complicate your clear request)
How cool would it be if you could just drag your root vault folder into a note, and the entire vault was mapped including all links to notes and folders?
