So the new builder functionality has deprecated the “copy previous” functionality.

There’s a work around, listed, but it only shows a static image. If I want to prompt additional exploration, I’m at a bit of a loss.

Right now, I’m leaning towards just making a straight up copy, without trying to transfer any state. Any variables I want the student to modify either cannot be imported (because the sink can’t be over ridden by user input) or needs to implemented in terms of deltas from the previous values. My stuff can get complicated enough that that becomes ugh.

What would be nice is if there was an initialCalculatorState sink that I could drop the previous one into.
