Note entry in version 3
One very bad thing I have found in version 3 is the result of pressing the backspace key during note entry. In version 2, when you pressed backspace, the note before the cursor was selected so you could adjust the note as though it were the last note entered, now you must press the left arrow key, adjust it then press the right arrow key to continue entering notes. This also makes it impossible to add a tie to the note without reentering the key. This is definitely a step backward from version 2.
