How Do I create custom themes for 6.5.3 (finger friendly buttons) and sense 2.5.1922
 

Have a TP2 (Verizon) running NRG's Leo 23518 01.14.2010 ROM. Wondering how to create custom themes to change the appearance of the finger friendly buttons on the bottom of the screen. Would really like something as simple as a transparent bar with rounded buttons so the background shows through like it does on the slider.
Also, running the NRG taskbar default in the ROM, how do I change the color of the background of this to transparent instead of black?
