Rated 2 out of 5 stars

I can create or modify an XNote, but there is no way its existence of is indicated in the messages pane. The column available, called 'Notes' does activate but its header remains grayed out and no icons appear in the column. This no matter whether an XNote was created post- or pre-TB3.

Just for now I will manually turn on the message's star icon to tell myself an XNote is there - but this will need to be worked out for other users whose usage of XNotes is more extensive than mine.
