I am not sure if this is the right place, or if Discourse Suggested Edits is the better place. However, it seems the plugin doesn’t save changes made in the composer when you close it. That is totally fine, especially since it’s still experimental, but it would have been nice to know…
And that’s the reason why I am posting here. The dialog which was removed provided this feedback, and I still miss it, because even though losing drafts shouldn’t happen, suggested edits is the 3rd reason within 6 months I’ve found where it would have helped me to catch this without losing my draft. Sadly, usually longer posts are affected by this, because that is the stuff I work on and close the composer in between.
