It would be amazing if you could implement an 'Indicator Light' widget, much like a button.
Right now you have to make an object and then change its color using labels and nodes and all kinds of complex things.... just to make a light!
Use a node to input a 0 or 1 value to turn it on or off.
Make changing colour easy.
You could even add features like 'flashing' or allow variable inputs for dimming, etc.
Please and thankyou
