Rated 5 out of 5 stars

I'm using it as a (very good) replacement for Message Notes Plus, the notes addon I was using before it was rendered obsolete by TB68++.
I've written a converter from Message Notes Plus to XNote++ to keep my MNP notes, see https://github.com/alehro/message-notes-plus/issues/3

This review is for a previous version of the add-on (2.3.1).  This user has other reviews of this add-on.
