Apologies if this was posted already, a search did not bring up anything. Here is the idea description:
It would be great if I could select some of the content in a note, press a shortcut and a new note is created with the content selected. The selection in current note is replaced with a link to the new note.
The title may be generated automatically from the content or a prompt may be displayed.
This would allow to quickly refactor larger notes while keeping the link with the parent.
