Microsoft is refreshing its OneNote site today as part of a broader plan to rebrand its online Office apps. The new onenote.com site has a refreshed design, but more importantly it now makes OneNote a lot easier to use on the web. Previously, OneNote users had to navigate through folders on Microsoft’s SkyDrive service to find and open their notebooks. The changes are being rolled out as Microsoft prepares to rebrand its Office Web Apps to Office Online.
