I'm very surprised there's not more capability for finding or filtering comments in the admin.
I admin a non-profit blog that has about 25 users (contributors, editors, authors). It is a very active site with lots of comments. The search function in the comments admin is maddeningly ineffective. There's no filtering capability by date, author, or email.
I have one user who has asked me to edit their recent comment. But it took me over a half hour to find it due to the lack of any real capability to find a comment based on these certain criteria (like date or author).
Is there some plugin out there that I haven't found yet to give me this capability?
