Gutenberg does a lot of things right, but these UX gotchas are killer.

I almost lost an entire post last week because of the autosave disconnect. (Thankfully I copied/pasted the content of my post into a local .txt file.)

Block quotes, especially dealing with citations, are problematic as well. I've removed citations from quotes only to find them still appearing on the front-end of the site.

Then, when I look at the source in the HTML Source view, I'll see the tag is still there, with like one character of the original cited source lingering there even though it's not visible in the Visual editor view.

They're not deal breakers, but they're annoying enough to throw you out of the writing flow.

I'm getting into the habit of just writing my work elsewhere -- Ulysses, Evernote, Word, whatever -- and then using WordPress to stage and publish the content after it's written and edited.

That's a bit much to ask of the average user, though.
