I think it would be a superb idea to have the ability to pan/view a drawing while also having the Edit Additional Prompts window open.
I like using EAP/Edit Multiple Product Prompts to at-a-glance review whole rooms, but it would have so much more functionality this way if I could pan around and double check which cabinets need finished ends, which ones should have removed bottoms, that sort of deal.
I assume it would be a similar functionality as being able to use the drawing while having Part Properties, or even the product workbook open.
