I like the dynamic search bar a lot. I wondered why couldn't the Inventory Search Bar allow my search results to become copied into a new Dynagroup using a click of the button. For example, at the bottom would be 'New Dynagroup...' and when you clicked on it, it would copy your search options into a dynagroup query expression.

The problem with defining a Dynagroup is you can easily mess up the query and you don't get any results back. The language also has also has a different set of variables, like 'resource.type' instead of 'type', which can be confusing when going back and forth.
