Some feedback: The drill style approach seems helpful, but needing the variable names to exactly match threw me off. It would be great if we could _relax_ this constraint via a toggle for drill mode. "Precision Mode" feels like it's misnamed; when it's toggled on it feels more like a "guided mode" since chunks of boilerplate are written for you. It would be great if exiting Drill mode remembered choices, such as what portions were selected.
Ended up deciding to buy a subscription, but looks like the site still says "82% claimed" and "17 spots left". I appreciate the one-time purchase model, but feel that it's a bit shady of a tactic.
