Allow me to resize My Day to be narrower (meaning smaller/no margins)
My Day is useful but takes up too much space away from the reading pane and message list. Please allow me to resize My Day so that its left and right margins are tiny or non-existent. Currently the mandatory large margins take up about 4% of the total horizontal real estate of Outlook, and 22% of My Day. Instead of paying a 4% real estate tax on empty space, I'd prefer to make my reading pane 7%-10% wider which would mean less scrolling and improved productivity.
It's OK if the default margins are big like today, but if I opt into a smaller My Day by resizing it, then I expect this preference to be honored.
