TL;DR
Remove all wires connected to the combinator at once by pressing some shortcut.What ?
If mouse is hovered on arithmetic/decider/constant combinator and shortcut pressed, disconnect all green and red wires from it. This feature already works for electric poles. Please allow combinators to be disconnected too.Why ?
This will allow to fix wiring errors much faster. Now you have to remove all wires one by one (which is awkward) or remove and place entire combinator again (thus losing its setup). Single click solution would be better for circuit development.I think it should be some new shortcut. We can’t reuse shortcut for electric pole cable removal (Shift + Mouse L Button) because it works different for combinators and other entities, it’s used to paste settings, which is very important.
By the way, if new shortcut will be introduced, it can also be used for electric poles to disconnect green/red wires only, leaving cooper wires for electricity.
