A large 'Clear all' button?

I would very much appreciate having a large ‘Clear all’ button somewhere in the search terms box, so it wasn’t necessary to use the rather fiddly two step method which is necessary at present. Incidentally, in my experience, this doesn’t always do what it says on the tin, either, and fails to clear all the fields, making it necessary to backspace over them.

Many thanks for such a great product!
