Slack Message Deleter
Don't work.
Doesn't work...
Unfortunately, this and other Slack message deleter extensions no longer work. It appears that Slack has changed the format of their URLs, so the extensions can no longer recognize when the page you are on is a channel or direct message. This will require some redevelopment before it works again.
