Requested feature overview description.
Add a new column to the post changes page showing the thumbnail of the post in question. If a post ID is specified in the search field, possibly this could be removed, but that might end up being more confusing than useful.
Why would it be useful?
This would significantly reduce the amount of manual labour involved in going through a long list of tag edits trying to determine which ones are valid. This frequently comes up when I discover a particular user who doesn't know how to use a particular tag, or sometimes I'm just searching for all additions of an especially problematic tag.
It would also have the handy side-effect of enabling me to tell which posts have been deleted before wasting my time clicking.
What part(s) of the site page(s) are affected?
