In Overflow version 1, if you ever needed to share your document with another team member, you had to either send your .overflow file or download the document from the Dashboard.
With Overflow 2.0, you can now explicitly share any document with people belonging to the same organization as you. While on the Editor window, select the “Invite Editors” option, search for a specific user, and click “Share.” You can also decide whether you want to notify the newly added document Editor with an email.
Documents explicitly shared with you can all be found under the “Shared with me” tab on the Launcher.
