It appears as though Cortana may be getting even smarter with upcoming builds of Windows 10 Redstone, as the virtual assistant may be gaining smarter text and app alerts. According to a screen shot posted on Twitter by @tfwboredom, a new settings toggle will enable this functionality. The description for the toggle reads:
Send Phone Notifications - Let Cortana tell you on your other devices when your battery is low and when you miss a phone call, text or app notification.
There is no clear indication of when we may see this feature become available, but it's great to see that it may be in the works. Would you find something like this useful? Let us know in the comments!
