The new version, 3.3.4, of HARMONY, is now available at my web site
www.greenhedges.com

You can now Drag and Drop notes from the Note and Pitch toolbars onto the score. (You can also drag and drop the preview icon, which copies the entire contents of the note clipboard)
This makes it much easier to create or edit tunes.

(BTW It works exactly the same as Paste After)
