I have 
    project, 
    sale, 
    sale_management, 
    sale_mrp, 
    sale_timesheet
    (and others...)
installed, but the Project(s) Overview smart button is missing from the Sales Order screen.
Under Technical Settings I have 
    Analytic Accounting, 
    Analytic Accounting Tags, 
    Show Full Accounting Features enabled
    (and others...)    
What do I need to do to create a project based off a sales order? (and get the Project(s) Overview button to show up?)
 
                        
I should point out I have Demo Data installed, so there are projects that already exist. (Although I want to create a new project from this SO.)
