Make new/unread emails more distinguishible from older/read ones by adding color background to row.
Although new/unopened emails have a slightly bolder (black) font and a small purple dot to differentiate them from older/read emails it is still a bit hard to quickly distinguish them when you are looking at them all together; so it would be very helpful if a lightly colored (pastel color) (like a light purple pastel) background be added to the row of a new unread email so that it can quickly be distinguished from other emails around it that have been opened/read. The background color will go away (turn white) once the particular email is read/opened (and can be turned back on if the email is "Marked as Unread" after it was read). This feature can be added as an option in the Settings area in case some people don't like it .... but I know It will like it a lot.
