I hope this usage is intended, because it’s very useful.
- A note (call it “Document actions”) has a number of items that need to be taken care off. Say, one is “PMP final version”. I select a line, and make a reminder for October 29 from now using \remind and the reminder dialog.
- In the calendar for October 29 I click the reminder “PMP final version” and click “New note with reminder”, which creates a new note with the name “PMP final version”.
- Now I have my original note (“Document actions”) with a line linked to that reminder, and a separate note for the day of the reminder that is linked to the reminder.
This is really useful because I can keep my original list of actions and have individual notes for the actions on that list as they come due, the “Related Notes” section helps keep track of these notes.
But before I start depending on this as a real feature, I want to check that the Agenda crew intends that things should work this way.
