There are two file's you'd need to adjust:
/modules/boonex/wall/js/outline.js
$(document).ready(function() {
$('#bx-wall-outline .wall-outline-items').masonry({
itemSelector: '.wall-oi-item',
columnWidth: 170,
gutterWidth: 20
});
});
}
Then: /modules/boonex/wall/templates/base/css/outline.css
/*--- Item main layout ---*/
div.wall-oi-item {
position: relative;
width: 170px;
padding: 10px 0px;
}
You can adjust the widths downward a few pixels at a time until you get another column. I'd suggest you turn off all caching and clear the cache folder while you're doing this. Just know that any changes to outline.js will be used by ALL templates. I'd start off by changing those 170's to 165's, and maybe the gutter to 18. Then you might adjust the padding a bit.
