It would be really handy to be able to sing into the mic while in the editor screen, and have the pitch number of what you sang show up somewhere on the screen.
I would also like to be able to play back the note that I have laid down in midi format by themselves, or while the mp3 is playing too.
The one command that is missing from the editor, is the ability to insert a new note at a location, or split the current note into two notes.
Finally, a record option would be ideal. You would choose record and simply sing along with the song and have that be made into a .txt file.
