add a plugin to simulate average finger size vs element touch target size?

[hchiam]

below is a screenshot of a blue hand dragging an item: (the item is smaller than the average index finger width, so on mobile/touchscreen, it can be hidden from view - e.g., might be a problem for precise placing of pins on maps)

i'm also curious to know if there's interest in adding something like this to devtools, since the default touch "circle" size seems too small in chrome devtools - @addyosmani
