Hi.
You probably already thought so for the new console, but I suggest a double-clicking on an object for display their properties. Also, if object is a node, in the properties left menu, it should add an option to manage one or more DCI's simultaneously (active, disable, edit, delete, etc. on selected group) and another to manage one or more interfaces simultaneously (manage, unmanage, delete, create DCIs for interfaces, etc. on selected group).
Best regards.
