I have a clear button that I can press and it removes all notifications.
Edit: Fail on my part. You want transparency. Go into Settings > Droid Concepts Settings > User Interface > Notifications Colors > then check 'Custom notification bar' and go into Bar color. From there just slide the bottom bar (the alpha bar) to the left however much you want and have transparency.
i tried that but it just changes the top part. i want the part that you have where you can see your homescreen through the notification window. Like when you pull down your notifications and can still see the titanium backup and all that stuff
