Very minor feature request, because I've accidentally done this a few times. Maybe it will help someone else.
When intending to export a single note, I have (mistakenly) gone to the note list, clicked the note I wanted to export, and then gone to File > Export. This actually exports every note.
I think this can be helped by changing the labels.
From Desktop Menu: File > Export All
From Right-click on a file Export note / Export to-do
Side Note: In researching what was happening, I finally noticed the "Note" menu. Seems like this could/should contain all the "right click" options for a note, including "Export Note"? It also has a feature called "Note Statistics" which is a cool feature, but I never noticed it before. Maybe that feature could be linked from the "i" menu or the right click.
