Re: contextual help on new features

[Richard Stallman]

    For example, the the first time "\pi" automatically turns into a greek
    symbol in the current buffer, you might see a message telling you
    what's just happened.  In addition to being informative, this message
    should have an "actionable" aspect to it -- specifically, the user
    could be given the choice to either "accept" the new feature, or
    "reject" it.  Upon accepting the feature, this particual message would
    go away.  Upon rejecting the feature, not only would the messages go
    away, but your .emacs would get set up with a configuration item that
    stops the feature from activating in the future.

It is an interesting idea to develop for a future release.
