It would be quite nice if the toolbar could be shown vertically along the sides of the screen rather than just at the top or bottom. On widescreen (16:9, 16:10, 21:9) monitors the vertical space is limited yet the horizontal space is in abundance. It makes much more sense to have the toolbar vertically on the left or right side in my opinion as it makes the remaining viewport less rectangular. Options to adjust the icon size would be nice too as they don't really need to be as big as they are.
