KNotificationAreaItem

[Robert Knight]

I'm thinking it would be a good idea to keep the number of ways of
interacting with an icon very limited to force application developers
to make the interaction 'model' simple.  Three choices, as provided by
the proposed API, is a sensible limit.

I know some KDE users would love the idea of being able to two a
three-fingered twisting gesture with medium pressure to change their
microphone input volume in KMix but that's not helpful when that piece
of the desktop UI is something which is meant to be used by a broad
audience including less technical users and users who don't have the
motor skills of a regular counter-strike player.

Regards,
Robert.
