Just a suggestion that I have made in my installation, on the contact's page enclose the notes section in <pre> otherwise new lines when entered into the textarea don't mean anything.
Actually the notes section takes full HTML as content and displays it as HTML. You can write <h1>Hello</h1> or put <pre> in as well. This allows maximum flexibility, at the cost of other things.
This may be desired or not. I should make an option to disable HTML in notes.
