An unfortunate part of the future we live in is photos surfacing in our digital history of people we'd rather not see again. Google has a way around that with the latest update to its Photos app on Android. Now you can hide a specific person under the People tab. As the Google+ post tells it, that'll keep the new grouped photos tool from resurfacing in those people under the "rediscover this day" tab as well. It isn't quite the level that Lacuna, Inc. works at but, combined with Facebook's similar tools, it could help save some heartache. It's rolling out to folks running Mountain View's mobile OS right now, with iOS and web updates coming "very soon."
