I notice the cursor moving now… but as Arjan said, it’s not very obvious that something is happening. As Arjan suggested, a green wave during playback may help…
Or here’s an idea… At the top of the file browser window, there is a little play/stop button. Currently, it’s grey/white like the other buttons… I see it turns into a stop button during playback… Maybe instead of turning into a stop button, it should just always look like a play button, and it could light up green when playing (like the standard play button), and go back to grey/white when not playing.
