New first-click test

Write each task as a situation, not an instruction, and never name the button you expect them to click. Add a screenshot of the screen they start from. Then drag on it to mark the areas where a correct first click would land, or leave it unmarked to just collect clicks.

Shown on its own screen before the first task. Say what you collect and what you do with it. Don't use screenshots with anyone's personal details in them: everyone with the link sees them.

Close a study when you have enough, or set a cap and let it close itself.

Add a screenshot to start: the study is saved as a draft from then on, and you publish it when it's ready.
