How about adding the used pins (data/clock, button, etc.) to one of the pages?
@tonyno What you mean by that?
Something on the Security & Update page, like…
About
WLED version 0.9.1
Pins: Button: 0, IR: 4, Relay: 12, Aux: N/A, LED Clock: 0, LED Data: 2
Could just be handy for me. 
Did you try - http://yourDeviceIP/json/info?
I just did and don’t really see much. It’s a start, for sure.
So some extra can be added. Make a request to add info to JSON. @Aircoookie will be happy to add some improvements
This seems like a request to me. 
Maybe we can just add it to serializeInfo in wled19_json…
JsonObject leds = root.createNestedObject(“leds”);
leds[“count”] = ledCount;
leds[“rgbw”] = useRGBW;
leds[“wv”] = useRGBW && (strip.rgbwMode == RGBW_MODE_MANUAL_ONLY || strip.rgbwMode == RGBW_MODE_DUAL); //should a white channel slider be displayed?
JsonArray leds_pin = leds.createNestedArray(“pin”);
leds_pin.add(LEDPIN);
Maybe instead of “leds” we do “inputs” and “outputs”?
