Today, Google released three new Chrome apps that allow you to access Google Docs, Spreadsheets, and Presentations in one click. I'm actually surprised that it took Google this long to make one-click access available through Chrome. The Docs app (each app is a separate install) allows you to create documents even when you're offline (this feature has been available through your browser for a while).
Installing each app is a one-click process that does not require you to restart your browser. Once the apps are installed you can click them to instantly open and create a new document, presentation, or spreadsheet. If you use the offline Docs app to create a new document when you reconnect to the web your document will sync with the rest of your online files.
