It's been about four months since the OneNote app for Windows received a significant update. Today, though, Microsoft is adding several key features, with the biggest being the ability to scan images and then search them using keywords. This new Camera Scan feature, as it's called, automatically crops and rotates photos, removing shadows and sharpening the image where necessary. Then, it uses optical character recognition (OCR) to search for words in scanned images, making it easy to find those meetings notes you took the other day.
Additionally, the update now allows you to save things using the Share Charm. And if you want a shot of the entire screen (and not just a specific item, like a recipe), you can use the Share Charm in a Windows app and then select" screenshot" from the Share Charm drop-down. (In desktop mode, screenshots are already the standard option.) Finally, the app now has both a full-screen view and a "Recent Notes" option, which shows all your notes in the order you last used them, regardless of whether you were viewing them on Windows, iOS or Android. These are accompanied by short previews, making it easier to zero in on what you want. And that about sums it up -- to get the latest version, hit up the download link below.
