I agree. In fact I think many of the items under "options" (and elsewhere) should be tied to particular styles if the user so desires. We are definitely going to try to work this out for a future release. Also a note regarding convenience. If you have MediaLab, it makes it way easier to administer multiple DirectRT input files. You can have multiple input files and you can randomize them (if you like), have practice sessions, and so forth without any intervention from the experimenter. Just a thought in case that helps.
