Subject: [PATCH] Adding feature - Show the controller briefly when adjusting
 speed and the controller is set to hidden. (#538)

Adding new feature: when the controller is hidden and the user changes rate, show the controller briefly. A new action called `blink` is added, and is called when the rate changes. Then if the controller is hidden, remove `vsc-hidden` and add it back after `value` millisecends.
