I work with quite long documents and to keep them manageable I reference details with links to notes e.g. Evernote, Simplenote, etc.
I can’t use Agenda for this even though it would be so suitable in many ways. The agenda link generated in x-callback-URL form is not recognised as a link by MS Word or Google Docs
I can use x-callback-URL links to link to a note e.g. in Things and some other apps, but it doesn’t work to reference a note in Google Docs or Word or iaWriter
