I am only on map 2, but I found something I like better from Sequence 1. It is the method of setting sequence numbers on each device. In sequence 1, changing the number on a device did NOT mess up the sequence numbers on any other device. I like that. In Sequence 2, changing the number on a device swaps it with the other device. I don’t like that as it causes me to fight with the sequence numbers to get them all correct.
Yes, in sequence 1, it allows you to have 2 devices with the same number and then gives you an error when you try to run the machine. I would rather have that than to fight with the sequence numbers.
Some may like method 1 better and some may like method 2 better. Maybe you can make it a user option.
