Default [Q] Modifying TouchWiz Launcher

Hello everybody,

i would like to have a transparent app list on my TW Launcher.
I already noticed [MOD] TouchWizGTG Launcher but the project is dead and it has many other stuff i don't need (i only need the transparent app list) and it would be good to have an up-to-date release.

However, how to realize the transparent background?

I already decompiled the apk file using apktools

Thanks and best regards,
Danny.

EDIT: Got the app bubbles removed (just replaced some mainmenu_...bg files in the drawable-hdpi folder with transparent png's)
But I still need some information about the app drawer background, where to set the transparency to get it 50% transparent?
I know: There are just 2 characters to modify (aarrggbb value) - but which value?!
