Focussed Window Audio

Feature
What is the current behavior?
Standard behavior is that all windows or applications pass audio to the OS unless otherwise configured. Many games will mute their audio if they are not the focused window but nearly all other windows behavior is to simply output audio. I've looked for other OS programs that implement this feature for all applications, but it seems the feature is application specific rather than system wide.
Expected behavior
I use multiple instances of pennywise to watch stream of multiple sports games on a single monitor. It works fantastic for this, but while I can watch multiple games at once and focus my attention on a single window of interest, my brain can pick out the audio of that window when 4 audio sources are playing. I can manually go through and mute all except the stream of interest, but this is additional work and time. I suggest adding a feature that can allow for non-focused pennywise instances to be mute (or only play audio from focussed pennywise instance). This would allow for quick navigation and audio selection without the extra hassle of muting and un-muting when I want to change my focus to the stream of interest.

We would have to add a mute button inside of the settings popover due to the fact if you clicked off it would no longer do anything. I will take a look into doing a mute sometime today for you
