Yes, you are right. More fine grained control is needed. Also, the
user should be able to control what apps or windows to consider.

You could define the screensaver timer as an event. Then this would be
part of the great OS level event system that has been discussed
earlier. One of the criteria available to the event system could be
whether the system is "idle", with the definition of idle being there
is no mouse/keyboard input and no application is telling the system it
is entertaining the user.
