Until today, I've avoided using the file Notes feature in Nautilus (Properties), because of portability problems. ...but they are just so tantalizingly handy! ...Adding notes to a like-named text file works, but requires more juggling that the Notes feature. 

So I've decided to give the Notes a try; now that I'm (almost) exclusively using Ubuntu ...(I'm past the point of no return ;) 

So a couple (or three) questions have come up. 

* Is this Notes feature exclusive to Nautilus?
* Is there a Terminal CLI for Notes ...like the CLI for [trash](http://packages.ubuntu.com/trash-cli "Package trash-cli")?
* Is there a tool which can batch extract/convert the Notes into individual similarly named text files (or something similar) for "portability"?
