Mute icon just below slider

[RichJack]

Hi, I've just come across your project which is great BTW.

Is there any chance of adding a mute icon just below the slider, like you might expect if using Windows for example?

Also, on my setup, the slider is not wide enough to accommodate the text 100 when the slider is at the top. My default system GTK font (openbox) is size 10.

Thanks
