arrange blog posts in alphabetical order

hi i'd like to order my blog posts in alphabetical order, rather than by date posted. Is there a code to help with this?
I also would like more than 4 columns, preferably 5 in the Blogs page.

This is the plugin you're looking for:

hm, is there a way to manually hardcode it though? i tried this, but the formatting of the page is off:

<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
 
  <script type="text/javascript">
      $(document).ready(function(){
          if( $('.blog-item').length != 0 ){
              var categories = []; 
              $('.blog-item').each(function () {
                categories.push({
                  categoryName: $(this).find('.blog-title').html(),
                  listItem: $(this)
                });
              });
              categories.sort(function(a,b) {
                var c = a.categoryName.toUpperCase();
                var d = b.categoryName.toUpperCase();
                return (c > d) ? 1 : ((d > c) ? -1 : 0);
              });
              $.each(categories, function(index, object){
                  object.listItem.appendTo(object.listItem.parent());
              });
          }
      });
  </script>
