New splitter functionality

[Shadowhawk]

What does the new splitter do in the case that it is set to output priority but neither side is set?

I want to sometimes set the priority to left sometimes to right but there are situations that it should work normally can this even be done?

Before i had to disable the belts going out of the splitter to get this working and i was hoping that the new splitter would actually make this easier and cleaner.
