You add it in HFS itself. If you want to add it from the template... yes you will need help, that might be a bit complex.

It is quite simple the way I did the tooltip.
Add this in [file], [folder] and [link].
item-name="%item-name%"
Add this under the similar code in live.script.js.
$('#item-name').html($(this).attr('item-name'));
And then finally, add this.
<dt>Full Name:</dt><dd id="item-name"></dd>
Its pretty much impossible to let more than one line appear on the item modules, without major modification of the whole template. Its either one, two, three line heights... it can't be as many as it likes depending on the name length... the design would just become a mess. It means a lot of changes to the CSS and possibly JS.
