I like how the historic of edited text is handled: a link on the post allows anyone to tell who has done which modification and who approved it if applicable.
On the other side, I have some difficulties to understand how the close vote history is being handled.
It seems that close vote cast using the post's "Close" link is different than the close vote cast through the review queue. Once a vote has been cast through the review queue, pressing the browser's "back" button allows to get the listing of other reviewers (it's such a strange feature I initially contacted StackeExchange support by fear it was a bug...), but this listing does not cover non-review close votes so the number of close votes here does not reflect the actual number of close votes for this post.
Why this difference? Why not merge these two kind of close votes? Or why at least not simply have a page which would list all close votes cast for a post (ideally with a link from the close banner)?
