I put a few pics to change my battery icon when its charging. How do I set it so all the images show up as the battery loses power? Also when I add themes sometimes not all of the icons change which is understandable. Can I copy an icon pic thats in the theme and rename it to the icon I want to change so that all the icons match the theme? Also I was wondering if I could do that to change folder icons that I made with catagories?
