I'd love to be able to set certain threads in forums to ignore so they don't trigger the "new post" actions, alerts, etc. on a given forum. Example: The Delta Skymiles forum. I don't care about the Lounge thread, but I can't not see it if I want to track what else is new in the forum. I'd love to be able to mark it as ignored, hidden, etc... like a "thread" killfile.
