After watching The Last Jedi, I’m considering having the Yoda disappear after the fight with Dooku, to reveal that he has not left Coruscant. Cutting to the footage of him in his meditation chamber after the Tusken Massacre. This helps explain his sudden limberness.
I also plan on exploring further other force abilities…
This way when Anakin complains that there are thing they are not telling him it doesn’t completely come out of nowhere.
