That would lead to absolute chaos on any of my worlds.
E.g. I have a big lab-part. If it doesn’t consume science packs, it turns off itself (power switch) after a while. I put the measurement of pack-consumption away from the timer/switch. Used a big pole for that.
And many, many more examples, and I’m sure for others, too.
@mrvn: click&drag: how would you connect one part with another, 1000 tiles away? I don’t think that’s practical and dangerous if there is already such a route in between, that you would accidentally connect.
