Requested feature overview description. Overall blacklisting toggle on /post/popular* pages (restore/'unrestore' all "BLACKLISTED" thumbnails to their normal thumbnails)
Why would it be useful? Cause people might want to be able to check blacklisted items, and they can't currently do this without actually opening the individual posts.
Toggling of individual blacklist lines, in the usual manner of /post/index/*, would be a superfluous waste of screen space, as there by definition aren't that many posts shown on /post/popular* pages.
What part(s) of the site page(s) are affected? /post/popular_by_(day|month|year)
(actually now I think of it, /post/popular_by_* is weird in that it does show thumbnails as "BLACKLISTED" rather than simply hiding them. But that's not necessarily a bug and in any case is a separate subject.)
