accessed via Right-click on the app's entry in the menu.
Allows user to keep any notes they like, e.g if it's a beta version - any test results; in the future for non-PA apps - from where they were obtained; even just a reminder of what the apps does, some names aren't obvious and some memories aren't what they used to be!
A nice touch would be to display, say the first line or until some indicator, the text on the end of the information that is displayed when the mouse hovers over the menu entry.
