Let ReadyAPI remember the last configuration that you used

In ReadyAPI you can use the GroovyScript. This window has by default a white background. You can change that background into a dark color, what I like more, as this is more soft to my eyes. Every Groovy Script in my projects have that dark color. But every time I close ReadyAPI, that color is gone and changes back in the default white background.

Is it possible to make ReadyAPI remember your last settings on this object please?

Thanks in advance.
