I like the Theme Studio application and use it to develop Themes for the 6131; but it does not seem to support mini-screen window simulations and the "Colors" under the mini-screen tab are not the ones that affect the text/font selections for the mini-screen. I would hope that this could be improved over time.

Also, there appears to be no way to affect the display of the time in the Main Screen or mini-Screen. A bit odd that these colors/fonts seem to be 'fixed' in the phone and can not have their color changed (or even turned off) by Theme Studio.
