Thank you for this script!

However, I prefer to have a smaller filter view, instead of having it stretched over the whole page. So I've replaced line 29 with:

     var html = '<div class="panel panel-default" id="utilities-div" style="max-width:350px">' +

thank you!

i migrate this to a repository with some improvements: https://github.com/sergiosusa/steamtradematcher-enhanced
