Mark all Read button?

While I appreciate the Unread category, it seems to only pick up topics that I have posted in, and not all topics that I have not yet read.

And there is the occasional topic that I am not interested in and thus do not want to spend time and clicks to get it to show as being read.

Is it possible to add a button/link which will mark all the topics in all categories as read, or at least one for each category that marks that category read? (ie: showing in the dim text as opposed to the brighter not-read-yet text)

@Farcaster following up on this request for a Mark All Read button or similar function.

Pretty please.
