Don't forget you can just zoom out and click where you want to be
might find that a bit quicker if it is taking you so long to scroll through your tiles.
Yes, there's zooming but my point isn't about being quicker, but about being more
organized.
Rather than have to depend on scrolling horizontally to access my apps/live tiles, I'd like to have the ability to drill down into various folders and subfolders into which I can place my live tiles.
Let me tell you that when I first learned about live tiles, I thought they were silly. But once I experienced them, I
loved them! As such, I always check to see what info a live tile displays in the various sizes and that's how I decide what size it should be. So I'm all in when it comes to live tiles; consequently, I need a more efficient and effective means of organizing them than horizontally scrolling through groups.
