Does v9 enable export of text link (made using ziplink) into formats such as [some descriptive text](target-of-link)? I did some digging in the XML and I can see how the link is represented (thankfully not buried in RTF like browser links), but as far as I can tell, there is still no way to influence the export format of a text link.
A possible solution is to introduce a property export-textlink-format whose default value is “”. User can specify format string, e.g., [description]($target.name) where $target.name specifies what property of $target to be inserted. In this example, it is the name of the target note, but one could imagine other sorts of target properties (e.g., $target.id).
