There is no active development of DeskNotes anymore - may BeOS rest in piece.
I've received a request for the source code of DeskNotes to be released. I've managed to rescue the code off my old BeOS partition, and have released it under a BSD Style license.
I've uploaded the latest version which was going to form release 1.1.0. Whether this even compiles is a mystery, but it may be of use to someone somewhere.
A couple of bug fixes, and a new feature! You can now click on a note in the desktop to bring the desktop into focus, and click again to edit the note. There is a new menu option in the replicant menu to launch the application version of DeskNotes.
