User notes are available in CAM, but there is no UI showing that a note is available.
1. A simple icon (ie like the locked and/or the operation type) for non-empty notes would be great.
2. Hovering over the icon would allow quick viewing (tool tip style) and clicking would open the editor.
3. The CAM preferences can add a checkbox to turn this on or off for those who want to preserve real estate.
All would be good but just #1 would make notes much more useful.
