Recurring events notes
I would find it useful if action item instances generated by a recurring action would show, for their notes, the notes of the recurring action that spawned them. I often put information in the notes that is intended to help me perform the task quickly, such as checklists, or links to reference information. Currently, it seems that I have to navigate to the parent item to see these.
Apparently such instances have their own note storage. I can see the value in this for taking notes specific to an instance, but for a recurring item I doubt I would want to do this very often. I would be happy with a read-only view of the parent item's notes. If having writable instance notes is important to some people, then an instance could start with a copy of its parent item's notes, although this might raise concerns about storage consumption. In that case, perhaps the copying could be an optional setting associated with the recurrence information.
I would settle for a button that takes me from a recurring action instance to its parent ...
