BigBusiness 15 lets you drag files to the Docs folder and now emails from Apple Mail.
Drag emails from Apple Mail and drop them on the Docs folder to save a ton of time. Other users can open the email by double-clicking and see any attachments in context.
To try yourself, turn on Docs if you haven't already, and drag a message from Apple Mail and drop it on the Docs folder, such as on a new order an email with a PO PDF.
