- removing kid anakin from the end battle (painting out any glimpses of him running around)
The best option is to edit out the kid stuff (get rid of the “whoops”) and show him activating the autopilot on purpose!
That makes his character much better, and in line with his force abilities.
Also disobeying (by going into battle) explains the reservations to his training by the council.
- many scenes with jar jar painted out (all scenes on tatooine and coruscant at least)
For me the only good scenes are the dinner at Anakin’s house and when Amidala asks him for help.
Even without painting him out, just removing his noises helps. As with Anakin, remove all those exclamations and little screams. They are there only to keep very young audiences interested.
You will see that the movie immediately improves just with sound editing.
