Allow the Layer Settings Dialog to be non-modal, meaning that the dialog will stay open like any other palette and allow the user to continue working. The layer changes could be live or add an 'Apply' button if that made the implementation easier. We all have multiple screens now, and I would love to park this palette on my second screen so that I can access this easily. And if anyone wants to close it, they would hit the 'OK' button just as they always have.
