Doesn't work.. I've tried, it completely screws ur computer.

Ok yes, I meant the body... I'm sorry for any confusion about the window opacity

Nope! The window, or the chat part of it anyway, is transparent... Have you even tried the theme yet?

Don't ask me, ask him.... And you don't change the window opacity, the maker of the theme sets it, tho how, i don't know... Look at pretty simple or actually try out his theme to see wat i mean by like the window opacity.

I don't think it has to do with background opacity... It has to do with the opacity of the window itself
