    secondLayout = [NSLayoutManager new];
    [storage addLayoutManager: secondLayout];
    [secondLayout release];
    [self addColumn: nil];
    [self addColumn: nil];

- (IBAction) addColumn: (id)sender
{
    NSRect frame = [columnView frame];

    NSTextContainer *container = [[NSTextContainer alloc]
                                  initWithContainerSize: frame.size];
    [container setHeightTracksTextView: YES];
    [container setWidthTracksTextView: YES];

    [secondLayout addTextContainer: container];
    [container release];
    NSTextView *newView = [[NSTextView alloc] initWithFrame: frame
                                              textContainer: container];
    [columnView addSubview: newView];
    [newView release];
}
