The question is how to move the taskbar to the left, not how to align the icons to the left in the bottom taskbar.
@Microsoft: please bring back the option to move the taskbar to the left. I cannot believe this option is removed, it's like removing the option to use a keyboard and mouse. Me and most of my colleagues and friends have the taskbar to the left of the screen for the last two decades. It makes no sense to have it at the bottom if you use an ultrawide screen. Because you lose a massive amount of screen real estate. Please listen to the feedback of your customers because this is the dumbest thing ever
