I created a Drafts Action to crosslink a Craft Note and an Omnifocus Task.

It uses the first line of the draft as title for the Craft note and the Omnifocus task and the full content of the draft as content of the Craft document. The title of the Omnifocus task will be a clickable link to the Craft Document

The Drafts action can be downloaded here: https://actions.getdrafts.com/a/1lZ
