Continuing bxtrx work on usability, spline have a better/easier behavior on editing, adding points as follows: adding points, will be done by setting on the action of adding points to spline. Removing points from spline is just to press Control and click on the point you want to remove. Pressing Shift will show the old dialog though (without the Remove button in case of spline's points). Are some small issue but I hope to address them tomorrow.
Inherited copies are used in Repeat Pattern tool as default. The new behavior will create multiple small shapes that you can modify individually. If you will want the old behavior, that creates a monolithic shape, you will have to uncheck the "Reference Inherited Clone" check box when the setup dialog will appear.
