Would it be possibe to add linked headings?

In much the same way we can list parents and children, would it be possible to be able to get a list of the links within a heading? Even if the list is just a list of text strings containing the link target?

Are you interested in only finding links to other org headings or any links in general in the body of a heading? The latter is quite easy. I think something like this should work (untested):

links = re.findall(r'(\[\[[^\]]+\]\[[^\]]*\]\])', heading.body)

There are probably some edge cases this regex doesn't account for but I suspect it should work for most links. If you want only links to org headings, I think you can write more regex filters to select only org headings from all the links returned by the above code.
I currently have no plans to further parse heading bodies into more components. That would probably be its own project as it would be quite complicated.
