Keep Temp/Pro-Forma Window Open in background when clicking an order.
When you are in the Temp/Pro-Forma management screen and you click into an order, the manager closes. So if you want to look at another one, you have to start all over again.
The original intention of this feature was to act as a streamlined means of retrieving a temp or proforma order, particularly for point of sale (POS) where you might have a customer standing in front of you. Like 'Find an Order' or other search mechanisms in CMS, they close after you've found/opened the desired order.
The other use case is, of course, 'managing' these incomplete orders in which case you'd want to have the window remain open as you work through them.
This window is probably a good candidate to have something like a checkbox for 'do not auto-close' so you can choose which mode you're wanting to work in (single retrieval or management.) CMS could remember that setting on your workstation so you'd only have to choose your mode when you want to change the behavior.
