Re: Perhaps a Good thing?
"All I would ask, is for some decent native CalDAV implementation. The Calendar plugins always seem a bit "tacked on" and not fully integrated, and sometimes will cock up."
From https://support.mozilla.org/en-US/kb/using-lightning-calendar-add-on
Starting with Thunderbird 38, Lightning is bundled with Thunderbird. This means you don't need to install it separately, but simply confirm to use it once you create a new profile or upgrade from a previous version of Thunderbird.
What's not, AFAIK, built in is Lightbird, an add-on to Lightning which provides a the calendar in its own window with a somewhat different and, to my mind, better interface. Native CalDav would also be useful.
