There's a section in the linked article about improvements to the taskbar, including the following:
> You can now quickly identify and access any instance of each app housed in the taskbar with just one click. All instances of the app are ungrouped with labels on the taskbar.
It makes it sound like you need to click a group first to ungroup it, but maybe there's an option to keep them ungrouped by default. I guess we'll see. You can catch a glimpse of what the labeled windows in the taskbar looks like in the Dev Home video embedded in the article.
