Awesome! I asked exactly for something like this 2 years ago :
But this is an interesting comment:
But now, with LLMs, I think visual programming is clearly a bad idea.
I have the same suspicion, but if there is still a textual representation of the code, then the LLM can write the textual code and the developer can use the visual representation to understand / validate the code. This could be better than textual code I assume?
