JobTracker app is great, make it track multiple cluster JT's at once!

Long time listener, first time caller. Great App!

However, it would be great to expand the Preferences menu to take a variable-size list of Jobtracker URL's, a human-readable label for the different cluster names, and times between scrapes for each.

One more awesome thing would be to have a checkbox by each one so that they could be selectively activated or shut down without having to re-add the URL and metadata.
