I figured out how to remove the "note" icon.
Just delete all the "NoteColor.png" files in:
c:/Program Files/RVG Software/HoldemManager/Images
(Or be stupid and put Fozzy's cool one's in the wrong directory!
)

PS: Only tested it one hand, then went WTF????
PPS: But then I don't know how you can read your own notes at the table.
