Works, but the view is bit cumbersome as it has scrollbar (vertical and horizontal) even if I am using a 27" monitor. It is filling only 1/4 of window. Would be much better when the JWT form is completely visible without scrollbars (and scrolling). I hope there will be an update soon :-)

Seriously helpful for anyone working with JWTs
