TL;DR
Connect bulks of entities (poles, chests, combinator...) by hovering with red/green wire or copper cable.What ?
Instead of click on entity, drag wire, click on entity, drag and so on, I suggest click on first entity, keep pressed, hover over all entities to be connected. Plus points, when the resulting connections are the shortest path between all entities.Eventually a niftier way: click on first entity, then keep pressed. If you want to add a connection see above, if you don’t want to connect to that entity press shift. Can also be used to bulk remove wire connections, which is currently a click orgy.
