You said you want to see what's playing now, but is that really what you meant? Are you interested in seeing more info on what is currently playing, or what will be playing next?
The point in looking at Playing Now is not to see the file that is currently playing, the point is to see what is about to play.
If you want to see the extended info (as shown in the columns of your file list) for the tracks that will be playing next, then Rod's solution is excellent.
But if you want to see info about the track that actually is playing, as you wrote, then perhaps you should consider customizing the info in the Player Bar, the panel at the top of the window that displays what's currently playing. Right click on it and select Customize Display, and you can have it show whatever you want about the current track. A lot of people don't know that display can be customized.
Plus it has the benefit of not moving you from your view. Rod's solution saves you a couple of clicks getting there, but then you add a couple of clicks to get back to where you want to be.
