New version; version 4
The previous version was somewhat dependent on chance. If you were lucky you would get the feature working in the first time the page was loaded, else you'd have to refresh the page a few times till the feature would get working.
With this latest code released on 6 July, that is no longer the case. The script waits for the other components to get loaded and only then does it do it's own job.
Hope you like the improvement.
