When I click the field for, in this example, the List to clear in the ListClear Server Action, OS grabs a lot of lists for me to Suggest, but as I type, that list is not filtered to those lists starting with what I have typed:

That's awesome. Can we just move this filtered autocomplete behavior up one step to the screen I shotted above?
