Some way to identify if a note exists
In each of the records you have the ability to add a "Note" Company, contact or Deal. The problem is that you are not able to see if a note exists without selecting it to see. Maybe similar to files show a (1) next to it to show that a note is available for that record.

I would think you could filter on the Note field; and select "field is Empty" or Not Empty
