I'd like to organize my headings in multiple ways at once. (with the same degree of flexibility that I have when organizing things in any one place - e.g. more than the Agenda provides)
Ideally I'd be able to make a heading in part of a document, and then create a "hard link" to the heading somewhere else, which would update both as the content of heading changed.
Next best would be "soft links" which only store the heading content in one canonical location, and just show it in the other location (and if you edit it in either, it just updates in the canonical location).
Right now the best I know how to do is just create normal links, which I need to manually follow to see the content. Is there any way to do better than this?
