Santa Tracker has clearly made its mark on Google -- things in Mountain View are beginning to look a lot like Christmas. But then, it's probably much too difficult to resist the urge to sprinkle in a few references to Kris Kringle in a post detailing updates to your list-making app. And surely many a holiday gift giver will be pleased with the tweaks to the Web version of Keep, including full-color notes, text scaling, new fonts and the ability to rearrange lists. Search has also been improved and Google's brought over a navigation drawer for switching between archived and active notes. Now Merry Christmas to all and so on and so forth.
