This code lets you show something like this:
|
|
|
|
+-----
|
|
| TOPIC MUTES [undo] [x]
|
|
|
|
|
| You muted stream Foo, topic Bar.
|
|
+-----
|
|
|
|
And then you configure the undo behavior, and
|
|
everything else is controlled by the widget.
|
|
|
|
Codewise it's a singleton widget that controls the DOM inside
|
|
#feedback_container, which gets served up by server.
