No button. Nothing. But this is experimental so maybe down the road...
这个评论是针对附加组件的一个早期版本的(0.2)。I tested with 102.8.0, and the button can be elusive. It seems to have problems with remote addressbooks, like CardDAV. When a remote update changes the displayed contact, the button goes away.
I should be able to detect that refresh and redisplay the button.
