MCM on "[Theme: Pinboard] JS performance tips"

I have tested the following and perhaps you would benefit from this...

I placed the following my child theme functions.php because

1. I do not use the Audio/Video player i.e. disabled mediaelementplayer
2. I assumed fitvids is to do with videos, but I use a custom plugin for videos so I disabled - fitvids.js

3. I do not use the slider disabled - flexslider.js

4. Also removed (related to poitn 1) the css

This is 4 javascript request less, which may help with performance.

// Theme Scripts
add_action( 'wp_print_scripts', 'pinboard_deregister_javascript', 100 );
function pinboard_deregister_javascript()
{

    wp_deregister_script( 'mediaelementplayer' );
	wp_deregister_script ('fitvids');
	wp_deregister_script ('flexslider');

}

function pinboard_deregister_styles()
{

    wp_deregister_style( 'mediaelementplayer' );

}
add_action( 'wp_print_styles', 'pinboard_deregister_styles', 100 );

Can anybody tell me what fitvids does?

Let me know if this works for you?

Also if you have other suggestions in this regard
