I have just started using this part of the program.  SO-P has a button to "SHOW OPEN QUOTES".  How do quotes get closed?  I can't see an option in Sales Order Defaults to set the expiration date.  
 
It would also be good to get the expiration date up in the Info box on the quotation form.  As it is, we have to add it into quote notes.  Same with estimated delivery.
 
Some of these options are available in the ES module (under manufacturing) but not the SO quote area.
