[External Links Enhanced] Disable built-in sites #726

Is there a way to disable some of the built-in sites? I'd like to have only the sites I visit frequently displayed with their own icons and the rest hidden in the link menu, so they don't clutter up the space and make it harder to find the icons I actually want to click on. I could obviously edit the script, but that would be overwritten with the next update, so I'm looking for a cleaner solution.
