Please allow to change icon.

This plugin is very useful. Thank you.

On firefox, I have changed music.youtube.com to ym. This is what is looks like:

I wish:

1. Change icon to a blank empty icon such as
   
   or default icon on chrome
   
   on firefox
   

2. Please remove the string "PLAYING"

Thanks.

Yeah that would be out of scope for this extension. I did consider creating a separate extension like this one but just for changing the tab icon (favicon), but I don't have the time
