This is pretty straightforward, but I think it's worth mentioning: - The dialer app should start up virtually instantaneously. It would be nice if the media player did too, but it's essential for the dialer. - I should be able to add numbers from my call history as contacts. - I should be able to select any text, and there should be a title bar icon (or some other always-available functionality) to paste. - There should probably be a power button menu option to restart X. (Ideally, we could edit the power button and aux button menus trivially)
I do think you should go with either Kevin Dean's idea of configurable data on the address book details page, or, more trivially, a remarks/notes section. I may want to remind myself when I called the person last, or a food allergy or lunch preference they have, etc.
