Notes are sometimes a bit difficult to see if u have lot of notes in the sequencer window for trance leads or you need to move them quickly to another location in the sequencer window. I.e to E4, therefore an added addtion would be if you move your mouse over the note a little dialog box appears telling you the note. If you move it from E3 to E4 and you drag it to that location in the sequencer window the dialog box will appear and the tell you the notes as you drag it i.e if u move it from c4 to e4, will see the dialog box note change from C4 to E4 if you want to move the note to E4. This feature could be enabled and disabled so if you have loads of notes the dialog box won't get in the way. A show notes check box on the sequencer could work.
