Questions about Notes interaction

I'm interested in adding note-taking functionality to all my courses by default. I have a few questions about the Notes interaction for Captivate.

1) The interaction as-is presents some serious usability problems, mainly the fact that if you click the X it actually deletes the note rather than just closes it, which is terrible design. Typically when you see a pop-up window with an X, you assume you are merely closing the pop-up, not necessarily deleting its contents. Could this be easily modified so that the interaction maintains all captured notes automatically through the entire course, ditching the Save icon and changing the X so that it merely toggles the notes pop-up closed without deleting its content?

2) Has anyone successfully integrated the Notes interaction into a player skin? Ideally what I'd like to see is a Notes button somewhere on the skin that opens a notes pane that can be left open across multiple screens/slides and closed/reopened at any point while retaining all previously-recorded notes.
