Thank you very much for ninja adding this back. <3

Any idea if this would work with a headless dedicated server? Would the server need any change or just the clients connecting to it using this would be enough?

Absolutely asinine decision to remove this based on "speed runners" and devs playthroughs. Not everyone plays the same way, and that's kind of the whole theme with factorio. OPTIONS. Many, many people used this and it really should be an option that is returned.

Please put this back! Makes building busses so much more difficult when you can't drag belts up and down while keeping them horizontal.

Why would this feature have been removed at all? It's a players choice?
