Mark all as read should only mark those shown in the list


Why is all as read marking those not even shown in the list as read?

I usually want to read the “important” articles first (those with green dot), so I will make it shown only green articles. When I’m done with those, I might still want to read those less important articles. So I click mark all as read hoping to mark all green articles as read, but it instead mark ALL articles read.

How should I make it work as I intended? Or how does newsblur support my workflow, namely show green only at first and then show those that are not marked green later?
