On the recent changes page the change in size that the edits make is shown for each edit. Could it be possible to get a similar overview for the edits of a certain user? The reason I am asking this is that the last few months it has happened a few times that my bot unwantingly removed a large part of a long page. I still don't know what caused it (my guess is that it's a problem in the internet connection causing only part of the data to be transferred), but if I had an overview like that, at least I would be able to do a check and quickly repair it where it has happened.
