Hi,
I would prefer the option that the messages only get marked as "read" when you really read them. It would be much easier to farm without loosing the overview when you scan a lot and you go through the scans one by one. If you just click at "Espionages" and the new scans lose the highlight you can easily lose the overview which one you already checked and especially when you farm inactives the highlights are a good marker, which one you already attacked and which one you have to attack next.
