Why can't TS handle that? Users always prefer to use the lowest level thing available, that doesn't mean it is right. In the language of TS what does a "funky system, liked mixed particle-field," mean, does it require a little more API on our side? I'm much rather have Emil and Jed control the time-stepping then some ignorant user. Barry
