About this Add-on
This add-on scans all contact-cards of the currently selected addressbook, extracts all categories and displays a list inside the Thunderbird addressbook. It allows to rename and to remove a category (changes the category string in all member contact cards).
To be able to use this Add-On, you need to have a CardDAV-Server (e.g. SOGo, ownCloud, Baikal) and the SOGo-Connector Add-On needs to be installed (to hook at least one CardDAV adressbook into Thunderbird).
The CategoryManager is part of a small CardDAV ecosystem: Besides easy access to CardDAV contacts via Thunderbird on PC (Windows, Linux and Mac), there is an equally easy access for Android devices (via app CardDAV-Sync by Marten Gajda) and for iOS devices (native CardDAV support). Furthermore, simple access to CardDAV contacts can be integrated into the web-based e-mail system Roundcube (via plugin RCMCardDAV by Benjamin Schieder).
The category-based contact groups are supported by CardDAV-Sync (Android), RCMCardDAV (Webmail/Roundcube) and CategoryManager (PC/Thunderbird).
