I'd like to see "Transparency" added as a dial that can be keyframed so you can fade objects over a period of time. It could be used to overlay two objects and create the impression of a morph from one to the other by fading out one as you fade in the other. Or better yet, also add the ability to link two objects and morph one into the other ( i.e., a human into another creature, a pen into a sword, etc.) over a user-specified time frame.
