I'd like to enter a plea for a bit more consistency between 'next actions'. please.
Sometime we have 'Click to close window', other times 'click to continue', sometimes 'back', sometimes nothing at all. There may be others as well.
These are probably easy to fix - the only changes are to the user display, not necessarily the underlying code. Maybe a post-it note thing for next time some item (especially popup windows) is being altered.
