There are three things for Episode III that I'm planning on changing slightly for an eventual v4. The first is the death of Dooku. I like the idea of characterizing Anakin as being affected by the Clone Wars by having him kill Dooku without external provocation. But, it happens rather quickly, and I wonder if it would be more appropriate to merely remove Anakin's hesitation but still include Palpatine's goading. I'd be interested to hear others' take on this; I have not heard any complaints about the Dooku change, and many other edits have done it as well.

I'd like to trim Windu's dialogue as he and Anakin discuss arresting Palpatine. I'd like to remove his line about regaining his trust. It would go like this:
A: I must go, Master.

W: No. [REDACTED] Wait in the Council chambers until I return.

Windu comes across stubborn and more abrasive this way.

I think that's a great idea for the Dooku scene. I've actually been a bit skeptical of the way most people edit that scene, but it seems to be a universally accepted/expected change. Would like to see how it flows with your new suggestion.

And I think the Windu idea is good for Anakin's character. The more distrusting and stubborn the jedi are, the closer it comes to making sense that Anakin turns his back on them. Windu's lines, as they are, seem perfectly reasonable, making Anakin just an impatient little twerp being put in 'time out'. It also fits Windu's no-more-bullshit attitude when he confronts Palpatine.
