you pick a basic shape to start from such as a sine or a straight line or whatever ...
... after this a left-click creates a 'hard' point for the line (this is basically the same as the current live automation curve nodes) ...
... a right-click creates a 'soft' point for the line (which works like a vector graphics spline point) ...
... of course once created all these points can be edited and moved as required ...
... although maybe just a simple 'simplify / smooth curve' button might be the best and most simple way of creating smoother automation ???
