I only wanted it for the "Remove highlights" option. That works well - I removed the rest of the stuff from the script. Other scripts on this site that claim to remove highlights don't work. This one does.
I tried a couple of the others and they didn't do what they were supposed to. This one works perfectly. It leaves the 'People you may know' and the 'Today' areas and I find those useful.
The right pane is now so much cleaner.
Good to see someone else doing the same thing as me :-)
Thanks for the 'Special thanks'
