Hello, sometimes the sound of the video in a horror movie may become shrill and we watch late night and the family is sleeping, so it is necessary to be able to decrease the sound quickly when we use our beloved GridPlayer and so it will be great to add an option to be able to decrease or increase the sound via the mouse wheel, and also manage increase and decrease the sound via the up and down arrows on the keyboard, thank you very much !
