I think it will be nice if we can "collapse" multiple deletions with the same deletion reason, by the same administration/moderation team member. This can be particularly useful in getting rid of large amount of duplicate deletion messages, spam, or flame wars. Here is what I vision it could look like:
There should also be some hover over control that would appear which would allow those with permission to expand the messages, and show them should they choose to do so.
I trust that some people will hate this idea (much like my mini-me recommendation which is now in use), and this may take some time to get used to. But overall, I think this will make the interface cleaner, and make a slightly better user experience.
