Add Font Size to watchlist properties, which auto scale the column height and width depending on the selected font size. It will give users chance to decrease the font size and free up space so they can view multiple columns and charts easily and not have to settle for 1 or the other. Attached below is the screen shot taken from my Mac 13inch. The column setting is at the smallest, and individual column width is decreased to the max. 6 columns and 2 chart layout selected.
