Drive, baby, Drive
Google Drive may seem like a simple storage service, but don't be fooled: With the right set of add-ons, it can serve as a powerful hub for cloud-based productivity.
Google has quietly been allowing third-party apps to connect with Drive for a while now. The apps add various features to the Drive interface, ranging from advanced file management tools to utilities that let you edit things beyond basic documents and spreadsheets.
We sifted through mountains of options to find the most useful ones available.
(Note that Google's sharable links for Drive apps all appear as add-ons for Chrome -- but once an app is installed, it'll connect directly to your Drive account and work in the cloud from any browser. If you want to install any of these apps without involving Chrome, click the gear icon in the upper-right corner of the Drive website, select Settings, followed by Manage Apps, then click "Connect more apps" and search for the titles there.)
