Can someone tell me how i can make transparent highlights, batttery and singal indicators and tabs indicators? I've tried to find tutorials but so far without any success. Sorry my bad english.

how you making a theme

The mask greyscale decides the transparency, a light grey will give about 80% opacity, the darker you go, the more you get, you can only do this on areas that have masks of course, and not all areas that have masks, support transparency.
