I personally include my worldbuilding notes in my word count when working on stuff for NaNoWriMo, so it’s unfortunate that the only way for me to have those writings included in my NaNo tally is to put them in the main draft. It would be awesome to have a toggle somewhere that adds up the word count of the main draft plus all notes for the NaNo widget.
Even if we could just see a word count on each note, that would still be fantastic since I could then add them up easily to paste onto the nanowrimo.org website.
