Foxtel TV Guide Filter (Bookmarklet)

/**      ==== FOXTEL TV GUIDE CHANNEL FILTER ("BOOKMARKLET") ====

    Helps you clear the clutter and see a listing of only the channels you watch.

    How to use:

        1. Add a new bookmark (any page) in your browser. Call it e.g. "FoxFilter".
        2. Edit the new bookmark in the bookmark manager -- or right-click on it.
        3. Paste the code below -- starting with "javascript" -- into its URL field.
        4. Browse to: https://www.foxtel.com.au/got/whats-on/tv-guide/grid/
        5. Click on your "FoxFilter" bookmark -- unwanted channels will be hidden.

        6. To modify your channels, edit the channel numbers below  (comma-separated).
           (The default listing includes "Entertainment" and "Sports" channels.)
        7. If you want to see all the channels again, simply refresh the page.
