I've made a new form field control for arrays of objects. The properties that go into the object can be specified and in this example I've used it to implement a simple gradient color node. This example can be viewed at https://demo.codeflowcanvas.io/gl and then select "Moving circle" from the examples drop-down (I just noticed a weird bug on iOS.. so please just try on desktop). Or it can be seen in action at .. nothing fancy at the moment, but I hope this allows for more fancy stuff in the near future.
