Microsoft has already revealed much of what's new in Windows Phone 8, but during its big announcement event today, the company spent some time demoing a handful of new features that we hadn't seen before. In addition to new apps for Facebook, Skype, and Twitter, Microsoft is expanding the functionality of the People Hub and adding a new feature to make it easier for parents to manage their children's use of their phones.

The new Kid's Corner feature creates a siloed environment where kids can access their favorite games and apps on their parents' Windows Phone 8 devices. Children can access the Kid's Corner even when the phone is locked, so parents don't have to unlock it for them. Parents can dictate what apps and games appear in the Kid's Corner directly from the Kid's Corner app.

Microsoft is also expanding its People Hub with its new Rooms feature. Rooms lets users group various shared services together, like lists, calendars, and photos in one place. Data that is stored in the Rooms is only accessible to those that are invited to join the Room. Microsoft claims that this feature works with iPhones as well, but it did not mention Android phones.

Additionally, Microsoft has added automatic image uploads from the Windows Phone 8 camera app. Images captured are quickly uploaded to a user's SkyDrive account, and they can then be shared out to social networks from there. Microsoft is uploading low-res versions of the photos to maximise speed and bandwidth usage, and it notes that you will have to sync your phone with the Zune Desktop software in order to back up the full resolution images.
