Here’s a (possibly?) controversial decision I’ve made. I’m keeping the Leia flying into the Raddus stuff. Poppa’s edit removes it, but I really think it works quite well in novel form for the following reasons:

There are multiple pages beforehand devoted to what Leia learned from Luke about the Force in her training.
No wonky CGI effects that make her look like Mary Poppins.
Descriptions of what’s going on with her body while she’s out in space which imo makes things more believable.

Honestly, the only reason I don’t like Leia flying in the movie is because of the CGI. I don’t dislike the idea in general (especially since it’s built up in the novel), so I think this works fine.
