When looking at the main list of emails it would be great if the lin/box of the read email could be a different color... like a gray background, or a color that could be set. I know the text is bold, but that is barely discernable. If the whole box was a different color it would make it easier to more quickly and easily differentiate between read and unread emails, for example when scanning back over the list to locate a read email that one needs to revisit to retrieve information from, respond to now that information has been gathered, or just once there is more time to attend to it. I feel like it used to be this way, but suddenly there has been an "update" to the look and now it is gone. If it is already currently a setting I can change I would like to know, as I can't find any info on that.
