The fullscreen interface has a handy button for changing the sound level. Unfortunatly, when you push this button, it both mutes and and pops up a slider. you will usually use the button to change the sound while you're watching something, so the sudden two seconds of muted sound are very annoying.

To make matters worse, the slider cover the button so you can't instanly unmute again. Instead you have to use the slider to reset what (you suppose) your sound level was.

It's just a small thin, but it's always bugged me.
