After the reply to extension is installed, the situation got worse. I am now getting two drafts saved when I reply to a specific thread. And yes, I am committing to reply and not bailing out in the middle. so, after the post, I have to go and delete two left-over drafts of the message. I am really really tired of this.
So, I think the auto-draft process is deeply flawed and I'd rather disable auto-drafts completely.
