What would make a good zettelkasten plugin?

But most importantly their is no UI to link to headlines within a note

I too find this to be lacking, but a workaround is to use the Outline Plugin which when you right-click on a heading, gives you the anchor URL. The biggest issue with this though is you must click to that note, then right-click on the heading, then return. A method of quick-selecting the heading while editing the linking note would be much better.
