With Paper, Facebook set out to prove that it could "think small," rebuilding itself from the ground up for mobile devices. This meant removing lots of clutter, and in some cases, leaving out certain features that some Facebook users might have considered essential. Facebook just launched Paper 1.1, an update meant to add back a few of Facebook's most important features, while continuing to think about how Paper can be different. Paper 1.1's most noticeable addition is the inclusion of Birthdays and Events, two of Facebook's oldest features. But instead of bundling the two into your News Feed as Facebook's main app does, Paper adds them to the Notifications screen. "We thought Notifications would be a good place to put this stuff," says Michael Reckhow, product manager on Paper. "These are the most time-sensitive things you need to look at every day."
