Hi everyone,
I’ve updated the feature request, UE-18302, to show that additional developers are requesting this feature. For checking on where wires are located, if you hoover over a wire for a short time that wire will be highlighted to show you where it is connected and will dull the rest of the wires.
Having said that, this feature request is currently backlogged as our resources are dedicated elsewhere, I do not have a timeframe of when it will be addressed.
