How do I disable the auto-updating of the Top Sites in Safari? I don't want to turn the feature off altogether, I just want to prevent auto-update. I know this may seem like an attempt to defeat the purpose of Top Sites in the first place, but I find that if it auto-updates any of the Top Sites that are forum-based, all of the unread topics are marked as read. So, an even better solution would be the ability to exclude the auto-update of certain URLs/domains, etc. Does that functionality exist?
