Let a right-click of the column headers provide the option to change the column layout.
It took me a while to find how to change the column headers (i.e. layout) because the option to do so resides on a right-click of a stock's row, not on the right-click of the column header row. Consider moving the "Layout. . . " option to the column header row or, better still, duplicating the option there for current users who are now expecting to find it on a right click of the stock's row. Should be a quick change that may well result in fewer calls since Telechart users coming to VV will already know where to find it (i.e., when it becomes available from the right-click of the column header row).
