[Plugin: Easy PayPal] It seems counterintutive that sandbox is not available in lite version

I am trying paypal solutions, finding that most of them don’t work. So I might consider the pro version of this, but would first want to test it with the lite version, and for me that means the paypal sandbox. However, if I have to buy it in order to test it in the sandbox, that just does not make sense to me.
