Activate Playlist Window After Closing Video Window
If you closed a video window in version 1.x, you'd be returned to playlist with that current video's name highlighted with the playlist window ACTIVE. You could then simply hit "delete" to remove the file from playlist, hit "down arrow" to select the next file, etc., without needing to first activate the playlist window.
In Version 2 when you close a video window, the playlist window is NOT made active (though, correctly, the previously shown video is highlighted).
