I think it would be very useful too as a means to edit the content of individual in context with other notes e.g. as a step to put together a longer story or text output. I’m sensitive to the fact that it is likely a lot of work as in essence a new view (instead of rendering individual notes).
Still it’s a recurrent and popular request (see for instance this post or this one). There was also a similar request in the backstage area recently which garnered some support.
