when you select an email in your mailbox, the colour gets only slightly more greyish, so it is almost impossible to see the difference. This can be quite annoying when you are searching for something in older emails, which have already been read, because you don’t see where you are on the list. And it becomes a real torture for the eyes to find out which message is selected… Maybe if on the left side of the rectangle one had a visual thing showing that this is the message selected, this would make it…
