Live preview

While you build a study, a live preview runs in the third column - the actual participant experience, not a mock. It walks the whole sequence in order: the intro screen, every question page, the clickable prototype with all its navigation, Variables and Paths, a 5-second exposure and its recall questions, and the thank-you at the end.

• It updates as you type. Change the task wording or a question and the preview reflects it instantly; structural changes (a new block, a different goal) restart the run so it always matches what will ship.
• Click through it like a participant. Navigate, answer questions, reach the goal - or press End early to preview the give-up path. Nothing is recorded.
• Start over whenever. Restart takes the run back to the top of the sequence, so you can check an early screen without rebuilding anything.
• Honest about what's missing. A prototype block with nothing imported yet, or a 5-second block with no image, says so in the preview rather than rendering an empty frame - which is also exactly what a participant would be spared.
• Out of the way when you want. Hide it with one click; the choice is remembered.
