I really dislike WP's Gutenberg editor. I can't find the stuff I need, like how to change the URL after publishing a post.

I don't think they are going to win many fans with this, and should not have tried to take it mainstream without ironing out more of the bugs first. Other WP block editors like Elegant Theme's Divi editor is much more polished and I think there are other successful examples. For now, I've gone back to the old editor
