Here are my Comments Comments.
I could not find anything about this so I thought I might bounce the idea off you.
A KEY CHANGE that would make the edit comments page better:
Allow the user to select how many comments are presented. (Ebay does this at the bottom of the page i.e. "see 25,50,100,200 items per page") Then, one could select the drop down box and select "mark as spam", then uncheck the "real" comments and push the button to take the desired action.
This would save alot of time administering a blog.
