Personally, I would like to see when you post a reply that the reply automatically shows when you submit the post. If you are like me, a few finger typer, you regularly post replies with mistakes that you then go back and correct. So every post I make I have to click “View your submitted post” in order to see/do that.
A minor issue but thought I would mention it to see if others agree and if so, if it would be an easy change to make.
Wouldn’t the Preview button on the post form work better for you for this? Once you write your post you can check it over for necessary edits, re-preview to check them, then hit Submit and go on to the next post. (The Preview button is down there next to the Submit button.)
