[0.15] Circuit Wire [fast] Drag+Connecting

[BlackKnight]

Just like the new copy+drag for recipes in assembling machines, I think it would be a natural and obvious progression to allow fast connection of circuit wires by holding and dragging (perhaps via special key + drag?).

Example. You have a number of adjacent inserters/chests, whatever.. - and need to connect them all. Or you want to connect a series of electric polls. This can be time consuming but with a click and drag it would be much faster.
