Basically that you can have a notebook-like workflow, without the cumbersome interface or unpredictable statefulness. And when you need to wrap it up for batch jobs, you can basically leave the code as is, since it can just take the widget default values in headless mode. Okay, so maybe a variable viewer isn’t a bad thing. I just know from personal experience that people get in the habit of scrolling through large arrays, instead of learning numpy’s slicing and shape concepts, or functions that detect e.g. the index of NaNs... I think that was mainly my point.
