I was just thinking it would be cool if with the switch module rather than having a 12 source setup which not have an adjustable version, so it would start with 2 ports, 1 would labelled Empty and the other Selector. Then if you added a source it would say Source1 and add a new Empty port, So basically you could use just the amount you need so you could have say 3 sources and there would be a empty input if you wished to add more and if you need more than 12 it would just keep going resizing the module the more inputs added
