Feature description

I think it would be really helpful to add a button to open background player from UI, the same one you access if you tap on player notification.

Why do you want this feature?

• On my phone I almost always loose player notification (idk if this is NP issue, even though NP is the only one affected), and regularly find myself in a situation when I want to edit the queue, but if I click on video I will almost certainly loose the queue (when switching from bg player to fg video player).
  Or even worse, I get completely desynchronized from what is currently playing, if at the moment of notification disappearance I was viewing not the video playing in bd. And the only way to access currently playing one is through history tab, but even then I do not follow automatically to the next video.
• Consistency, there's no other way to get to that menu other than player notification
• it could be used later for improving fg video queue - current way is workable but limited, one cannot save or shuffle current fg video queue, for example

Additional information

I have a feeling that implementation of #8353 would be a stepping stone for mine issue as it would make sure that queue does not disappear while transitioning from bg to fg player
