So under Comments you'd see New, Suspected Spam, Approved, Rejected. Suspected Spam would include all unmoderated spam?, while New would include all unmoderated ham? Makes it easier to approve the actual comments if your site is being bombarded with spam. What do you think? If I find some time I could work on it.
Aren't they currently under "Spam"? Are you proposing that there be two locations for spam with one being spam that wasn't directly accepted as spam yet?
I don't see a "Spam" category for comments (e.g. in admin/_submenu.html.erb) -- just New, Approved, and Rejected ..?
Oops, I was thinking of refinerycms-inquiries which has this feature as implemented here and here
