I just made complex edits that took a very long time to prepare, and therefore I applied the changes in one section of the article, then in another. Between my edits to the first section and my edits to the second one, a bot had restored some citations, which I had planned to take care of in my second edit. Unfortunately, I had to manually check every single box to override bot changes, about 60 of them. This tool absolutely needs a checkbox at the top that allows an editor to apply all changes in the right-hand version. Trust editors not to abuse this.
This is not an isolated incident, it happens to me often, including when reverting vandalism. This time was very time-consuming though, so I took the trouble to file a report here. Hope this helps.
