Feature Request - Text file annotation for each node from right click menu.

[Pcrossley69]

I currently document my projects using Annotate-Edit Readme.

However I find this cumbersome on large projects if I want to document the purpose of individual nodes.

I would like a right click menu item on each node which would open a small text file.
This could be used for documentation but could also be used to hold configuration that can be pasted into the node at run time.

As a trainer this would be very useful for teaching:
The main annotation would refer the student to the steps under each node.
