I had a tough time telling a colleague of mine that there wasn't the windows ubiquitous CTL-F to find in a note.  I showed him the workaround for typing in the word you're looking for in the note, highlighting it, them pressing CTL-F3 and he looked at me like I had three heads.  Then I showed him how to search using the CN main window.  My headcount was reduced to two.  But he walked away from CN amazed that it lacked what every other text or notes editor he's ever seen had ten years ago.  To each his own, but he does have a good point.
