In addition to creating new documents, Onehub's Google Drive integration also allows you to edit your existing documents. After connecting your Google Account, an Edit button will be displayed on the file preview page of supported documents.
Click Edit. After a moment, a Google document editor will be displayed where you can start editing the file.
When you are happy with your changes, click the Save Changes to Onehub button to update the file in your workspace. If you would like to abandon your edits, click the Discard Changes button instead.
