title: change or add data to Sidekiq Web UI
body: <p>I'm using sidekiq Pro and usually monitor my workers' process on their Web UI. Whenever there's an Error, the task is moved to Retries tab where the queue name and an error messsage are displayed. The thing is I would like to add data to this message (specifically class name and line number), but i havent found information about this anywhere. Is it possible to edit/configure the Web UI display? If that's so, how?</p>
