You use move*() methods to move things around. Such methods do not
depend on or change the duration of the event so they would go in the Spot
interface and you would be still able to move F around.
Moving an aggregate would move all moveable contained objects.
On the other side stretching a function table doesn't make sense so it
will not have such stretch*() methods. Doesn't it sound good?

There are no problems with csound scores. I'm using Sample tables right
now, for example (as attachment of course). But all the code related to
Csound scores is bad placed now. I have to take some time and think of
it.
