Clean and nice.
I think you forgot to put jQuery.noConflict(); in your code because you already use jQuery() instead of $()
So for people with trouble with mootools.js (or similar) at the end of line 79 just add jQuery.noConflict();
Correct:
$script = "jQuery.noConflict();
jQuery(document).ready( function() {
(...)
I changed too, the title of links to support language translations.
$title=JText::_('opentab');
line 88: title=\"Click to open!\" and
line 92: title=\"Click to open!\"
by
title=\"$title\"
add to /language/"your_language_code"/"your_language_code".ini
OPENTAB=Your Translation
thanks, I will add for next release.
