Why is there a Read filter, but not an unread filter?

On the top of a category, we can filter by a bunch of things:


Which makes sense! But it seems strange to me that there’s a “read” filter - why would I want to filter by questions I have already read? Unread seems like an obvious thing to have there, so I can find things I haven’t read yet.

So maybe either add unread or just change read to unread?

I believe it dynamically appears and disappears based on your unread status. At least, I’ve seen unread before but never with no items listed.

A bit later…
