Rated 2 out of 5 stars
Great idea, but it ended up being useless to me because the URL field is truncated until unreadable. Adding a way to read the URL would immediately change this to 4 stars for my limited uses. Adding script types/classes/categories as well as URL viewing is closer to what I image as 5 stars.
EDIT (6/13/18): The URLs mentioned above are those pulled down from the toolbar icon.
Which URL field? the one in the Options page?
