Replacing the 'x' remove button

Hi,

Looking at the results of adding a file, I think the 'x' to remove the file is a bit hard for users to see or understand. To fix this, I implemented a CSS image replacement call like...

a.MultiFile-remove {
  content: url(/sites/all/themes/bartik_essp/images/remove_file2.png);
  overflow: hidden;
  vertical-align: middle;
}
div.MultiFile-label {
  padding: 5px 0px;
  border-bottom: 1px solid #ccc;
}
div.MultiFile-wrap {
  padding-bottom: 7px;
}

Where the PNG file is an image I created. Here is a screen grab - I may need to fiddle with the image - text alignment. Also added a little padding to separate the divs.

I'm wondering if this could be added to the module or perhaps noted in the documentation as a solution to the issue.

Thanks, Eric
