Inverse Lightning enhancer plugin enhances the
functionalities of the Lightning calendar plugin
for Thunderbird. It is meant to add better
integration with CalDAV compatible servers such as
SOGo. It provides support for CalDAV freebusy
information in the scheduling interface and in the
addressbook. It manages the iCalendar organizers
by taking into account the identities configured
in Thunderbird. And it fixes bugs found from time
to time in Lightning which are not yet fixed
upstream.
