Would be a 5* if there was an option to keep the app open so I could have youtube music in the sidebar while working and just close it and it still plays music.

I there a way to prevent links from other domains to open in a new tab so I can fluently navigate always inside the sidebar?

Kudos to the developer. One simple request. Can you add an option that gives an URL for Open In Sidebar to open by default. That is whenever the side bar is empty after say it is toggled from History or Bookmarks.
