All right, here’s what stands out as far as big changes that remain unrealized. There’s plenty else to tend to but these are the more important things:

Mustafar. Does anyone have the high quality clips to use! LILLIAN posted a clip recently in her (?) thread, which used these. They are an arial shot of a patterned lava flow, lava eruption behind trees, and video game footage of troop carriers landing with troopers dispersing. And, if anyone wants to really knock it out of the park, add illuminated specks between the Destroyer and the planet in the film’s opening shot and troop carriers in some way to the arial shot of the lava flow (perhaps passing by camera closely so as not even to need a model).
Dominic’s version of the vision during Rey’s remote training, once he finalizes it
The squeaky wheel extension needs FX work, but is hardly essential
Luke’s haircut, if jonh gets it to where he is happy with it
Relacing Endor with Coruscant in the celebration montage (and Jakku with Kijimi, in a perfect world)
Final scene: adding Ben’s ghost from jonh, possibly add light double rainbow to homestead, and alternate take of Rey’s line from poppasketti
