Google today announced a series of updates to Google Docs which are sure to please everyone who relies on the free cloud-based service. The documents editor received additions such as a margin ruler, tab stops, comments, a re-worked system for placing and maintaining bullets and numbers and support for real-time collaboration of up to 50 people. Spreadsheets now allows for cells to be edited from the forumla bar, the use of auto-fill and the dragging and dropping of columns. Overall, everything is said to be much faster, smoother and intuitive. There’s a whole bunch of other changes we haven’t gone over, so why not hit up the jump to watch a quick little into video and then explore the service for yourself? We’re loving the realtime collaboration improvements.
