Duplicating notebook

[the-real-crayboy]

I have a notebook named IN
In config.sh I have
DEFAULT_NOTEBOOK="IN"

when running joplin-mail-gateway it created a new notebook called IN which it used for emailed notes
I copied the notes into the original IN and deleted the new one
New emails never showed up in joplin. ( Although it appeared the script was processing them )

I have started over - and again have two IN notebooks.

I guess I could copy all the notes from the original IN to the new one, and delete the original - would rather not!

Any ideas?
