Idea. (partially inspired by: PainBaller's comment)
To make it easier to move multiple connections at the same time
On the (left?) side of the screen, there cold be temporary connection points (like 10+ points? up-gradable?), like the Big Merger/Splitters, where you could hook up several connections to (with some kind of marker icon, or a hover-preview of the machine it is connected to?), then you can move to the other side of the map, or wherever, and un-hook those connections to grab the connection-thread so you can attach it to the actual destination.
In that way, you can bring over maybe 10+ connections in one go, instead of making 10(x2) trips (back & forth) to do the same work.
------
Maybe some kind of "multi line" connection (similar to "Oxygen Not Included"s "Automation Ribbon" that can carry multiple signals in the same wire), just so it is easier to organize a "main buss" of resources across the map, without it looking like a drugged spider has been puking webs all over the place.
