So I have a Sansa Clip+ using the Classic theme. I've modified it slightly (The .wps file) and have added a .fms file and changed fonts and stuff. The only thing left that I want to do is add a battery level symbol to the right of the top bar while browsing the menus. How would I go about doing that? (I'm thinking I'll need a sbs file, but there's not one there now, so how would I add it without messing up the current settings?)
