StatusHUD removes the obtrusive HUD when changing your volume and or changing your ringer state. Users can opt to have the square style HUD icons or the circular iOS 7 type icons when adjusting your volume.
StatusHUD puts the volume HUD in the status bar. You can choose either square or circle style. It supports showing volume and ring/silent state.
The tweak has been submitted to the Bigboss repo and should be available soon. The price of the tweak is $0.99.
