So Denemo becomes a program which differs from the conventional wysywyg
programs only in how you edit the music - you can even click on a note
in the typeset version and edit it directly using pc-keyboard or midi
keyboard.
Of course, the option of editing the LilyPond text is still there, but
most users will never do that.
I propose making the default be to display both typeset and music-entry
view and make the update continuous, with preferences settable to choose
otherwise.
You can play around with the continuous background typesetting using the
version currently in git.
I think this is such a change as to warrant moving to version 1.0.
Comments please!
