Google has made add-ons for its Docs and Spreadsheets. Browsers have had add-ons for awhile and they make your like easier. Most of them anyway. I am personally a fan of the EasyBib add-on. Anything to make the bibliography portion of a college paper easier will be greatly appreciated. There are more ranging from Charts and and label makers to signatures and messengers to discuss changes to a spreadsheet. The add-ons are live now so log in to your Google Drive area and check them out.
