Ok, watching Empire on Spike just now and I noticed something else that can be fixed - not an error, just an "improvement suggestion".

When Luke goes out the window during the final duel, in the shot immediately before, his saber is still on and in his hand. In the shot after, he's hanging onto the ledge and the saber is powered off and sitting at the bottom left. Is there a way to animate a saber powering down and tumbling out the window along side him?

I'm sure Vaderios or someone else can whip up a before/after to show what I mean.
