The menu item for "Add new object" is greyed out when the focus is not on the table. This is counterintuitive as the focus when navigating the browser is usually on the sidebar with the list of Models, and there is very little visual distinction between the focus being on the sidebar or on the actual table. So you end up wondering why you cannot add new objects.
It should also be possible to right-click the table to get popup menu with the option to add new objects (like you can get for deleting objects).
