is there a way to configure a circuit signal to detect weight? would be very useful for mixed cargo and remote launches.
I don't think there's currently any way to do that. Launching when a certain weight threshold is met could be a worthwhile feature to add. I don't have a lot of time for mod development these days but it's something I'll keep in mind for the future.
