Yes. I usually listen to one audiobook at a time, so I'm looking for the play button as soon as I open the app. When the player is closed, the play buttons are quite small.

But you're right - I haven't found another app that does this.

I see, thanks :)
I’d love to have one, even if it’s just removing the background and not changing anything else. I’m currently using a shortcut, but it’s more of a workaround than a solution.
