Usability people usually advise against having the same configuration in two 
different kcontrol modules.

No, in this case it cannot be solved with a good default. By default, no 
notifications need to be read. And normnally, the users don't need to be 
bothered with tts configuration stuff in the notification dialog.

But for partially sighted users, it is important to be able to switch that 
feature on easily. That's why we have a single checkbox in kttsd to read all 
notifications.

Anyway, this technical switch does not demand any changes in the user 
interface at all. The KNotification class can simnply always send a singnal 
to kttsd, and if it isn't installed or is not configured to read the 
notification, then it can simply ignore it.

Another possibility would be to always use the new notification deamon. (If 
that is technically useful.)
