Speaking of which, I was wondering why my MUA didn’t put a one-click unsubscribe banner at the top of my mailman lists like it does for lots of other “mailing list” email I get.

I realize that it probably hasn’t been implemented due to your separation of Core and Web. But are there plans to provide something?
