+1 to have an option to generate spatial index automatically for intermediate layers. As I understand, creating index for database layers automatically may not be preferable, but it's reasonable to want this for intermediate memory layers. Since processing can already identify which operations might benefit from the index, it would be much better user experience to take care of it internally.
