I found that annoying on the editor, but if used on a 2nd screen to build graphics programmatically (fractals, etc), or via an external port to drive RGB LEDs arrays or matrices, results could be spectacular. Imagine fractals driven by music or a giant spectrum analyzer made of LED strips.

I recently bodged together a board that would drive FastLED programs parameterized by the control voltages that come off a eurorack, it was really neat and straightforward because you have some really good clock sources to sync to
