It would be cool if it was just a specific "feature". But I feel like you have more control using fade envelopes on the Opacity slider. Which is discussed on this thread.

Only downside right now is it has to fade to down and then back. That is where some overlap would be handy. So yes, it is not a true "cross fade" yet, but very close.
A handy tip is that you don't have to go down to 0% opacity, so its really not too bad the way it is.
