I am having some serious issues using the track controls on this device (Nexus One).  It's hard to tell exactly where to press on the icon to get the functions to work.  It seems that I need to press above the icon, but I'm not quite sure.  Sometimes I press >> and the volume turns up really loud.  Sometimes I try to adjust the volume by touching the slide at the desired level, and instead the music pauses.  

Is there a way to make the icons bigger and maybe even outline them so there's no mistaking exactly where you need to press?
