This question already has an answer here:
Can we get an option to stop the global inbox from marking everything as read?
In the SE dropdown inbox list, when you view it, all unread comments/answers get toggled to 'read' if you view one of them. Is there a way (of course there is; is there any support behind...) to make this per item rather than global? To set to read by comment/answer instead of all at once?
My reasons are duplicated in Can we get an option to stop the global inbox from marking everything as read? but somehow the answer interpreted that question as simply asking for this as a preference. I am asking for this as the way to do things. Similar to how in RSS or news group readers you know what you've attended to and what not attended to.
