What do you think about those visual tools, especially in ML? There are some successful ones (like Rapid Miner) and aspiring ones like Luna, but I'm not convinced. I think they want to target a layman for whom they are too difficult to use (because building a model requires a technical mindset) and advanced users prefer to write a script. It is tempting to try to build something similar, and I am trying myself, but I want to avoid this trap. I am thinking about a tool that would take some burden from the advanced user leaving all the power and access to raw code.
