Google Mail users will be familiar with the Priority Inbox. This is an optional feature that attempts to automatically sort your incoming e-mail into groups: Important and Unread, Starred, and Everything Else. You can mark e-mails as important or not important, to help train your Priority Inbox. You are not limited to just those three categories. You can set up a priority view for other Google Mail labels – messages from the court, for example – so that they appear as a priority group of messages.
Now you can add the same sort of organization to your Google Docs account. Check out this Lifehacker post for screenshots. The revised Google Docs interface now has a right hand column where you can see a thumbnail of a document and, below, see in which collection it is contained. Unlike a typical folder structure – but just like the labels in Google Mail – you can place a document into multiple collections. Your list of collections appear on the left hand side of the screen, making it easy to navigate through your documents. You can create sub-collections too, keeping that folder structure vibe alive! Click on My Collections in the left hand column and mouse over the collection you want to add a sub-collection to, and you will see a menu called Actions appear at the right hand side of the screen. Click on it and select New and then Collection. Type in the name of your new collection and when you click OK, it will add your new collection. You can now start to organize content into this new entity.
