I recently upgraded to Microsoft Windows 10 and I'm trying to get used to it. The "tiles" for each app are useful, and I am using the Mail Tile to access emails. I can't get at my "Contacts" though - which are on my Yahoo Mail screen. I'm having to go to Google, then to Yahoo Mail and my old mail etc page. Is there any way I can get my contacts onto a part of the Windows 10 Mail Tile, or onto an app on my desktop  screen?
