I’m sure Ady is pretty set on his additions and changes now, but I thought I might throw out one other idea.

At the end of the final space battle, I think a shot of Star Destroyers scattering into hyperspace would be an interesting addition. Not only would it give a little more context on what happened to the rest of the massive Imperial fleet (did the smaller rebel fleet destroy them all, did they surrender?), but it also could foreshadow the eventual return of the Empire as the reformed First Order in the next trilogy.
