use theme functions to format blocks à la Drupal instead of hand-rolled HTML

there should be a (per-user) setting for the maximum length of HD blocks before paging occurs: lists are currently unlimited

there should be a site-wide setting for these values, acting as a default prior to user settings

Determination of customer status is currently inconsistent and distributed: as of 2005/11/06, function _helpdesk_is_customer is not used, and various checks are performed at various places in the code, some being based on the hd_user.uid == hd_user.uidcustomer test, while is_customer is role-based. The hd_user-based test might allow for removal of the customer role altogether, to simplify (?) administration

In admin/settings/helpdesk, only offer for selection vocabularies that can be appplied to the HD types (from vocabulary_node_types)

When 4.7 is released and HD ported to it, include settings validation.

a HD user can define whether (s)he wants one of the blocks made available by the module on his pages. A per-user setting could be added to define whether users wanting the blocks want them whether they are empty or not.
