Change responsive from 600 to 767 to cater for more mobile phone please

I love this plugin – always have – however I do have to manually edit the shortcode.css file everytime – please can you change the max-width from 600px to 767 px – that way the landscape samsung devices also pick up the blocks

/*@media screen and (max-width: 600px) {*/
@media screen and (max-width: 767px) {
.full_width,
.one_half,
.one_third,
.two_third,
.one_fourth,
.three_fourth,
.one_fifth,
.two_fifth,
.three_fifth,
.four_fifth,
.one_sixth,
.five_sixth {
clear: both;
width: 100%;
margin-left: 0;
margin-right: 0;
margin-bottom: 1em;
}
}

Although I must admit it would be great if this CSS was not pulled after the default css so you are able to override these details ?? but cannot have everything

Still love the plugin ??
Thanks
Sarah
