I'm a signature field, you can "sign" something here or make a doodle, i can be different colors too other than black, so i'm gonna be purple!

Interactions: Interactions are any time the form field is interacted with (like click, stop/start typing, selecting, etc). A high interactions count could indicate the user(s) are changing the answer/reply several times. This stat could be useful to maybe better word the question/field or maybe consider change the field type if it is one that requires the user to add input.
Impressions: Impressions are anytime the user's mouse enters the form field's area. This stat could be used to better understand how users are interacting with your form.
Time: Time is how long a user(s) are inside the form field's area. This could help you better understand how long your users are spending on each type of question.
