Ok, so I'm still stuck.  I've got the transparent notification background all set.  I need some help changing the color of the actual item line, it's still gray.  I know where the .png is but I don't know how to change the color so it will stay.  I changed it to black which would be fine but I guess I didn't do it right, it didn't take it.  (although I would really like it to be transparent too like ReGReT had on the screenshot).  So can someone walk me through it?  Thanks.
