Not that I've seen. Zonx usually gets a new relase done not long after the content goes live. On test your best bet is to use the default window. Sometimes folks might make patches but even then it's still very early in the test cycle. To my knowledge the GU hasn't been pushed to test yet and thats when the bulk of the UI changes usually go in. The character window is more related to the housing update so it's kind of off-cycle.
