Reviving an old post, but I wanted to stress how something like this feature suggestion would be a game changer for programming logic...

I recently rewired my GHL setup, as I moved it to a new cabinet.
I have a P4, KHD, 2 x Doser 2.1, Maxi Doser, 3 x level sensors, Flow sensor, Vortech pump controller, Leak Detector, 2 x temp, PH, redox, GHL Fan with speed controller thing, 2 x power bars and Red Dragon pump control.
I have two splitters cables, two expansion card and wires coming out of my ears.

I have twelve programming logic gates and so much logic at so many different levels of (sensors, control circuits, sockets, etc etc).

Rewiring the P4 was a nightmare, as unless you plug the sensors in the exact same port, obviously it doesn't work, but you don't know whats wrong.

I had to sit and go through each programming gate individually, testing each of the 12, then work back to the control circuits and sensors to figure out what specifically was wrong, and then testing each of the sensors.
Rewiring took me about an hour, fixing the subsequent issue on such a complex GHL setup took me about 10 hours.

Simply having a traffic light (or similar status) against each programming gate would have made this process a million times easier.
Likewise, in the connect app there is no description field for the programming logic, you try remembering 6 months ago why you did something the way you did it.

Please improve programming gates, please.
