Is there a point to calling JHtml::_('jquery.ui' array('core', 'sortable'); ? At the moment, if only sortable is loaded, it will automatically add in core as well since it requires core.
I am assuming at some point in time these frameworks should be moved to their own pages...I just don't have time to organize them and am filling them in as I work with them.
For Mootools, am I correct that it will be removed in the future? Ideally, the Joomla libraries should be first as it would be preferred to use Joomla namespaced functions to ones tied directly to an underlying framework - but until they are divorced from Mootools I don't want to encourage their usage[with the potential for conflicts between having 3 entire frameworks included on the same page].
