I thought it was perfect when I first started using it and I loved reclaiming so much screen space back but I found after a while when I clicked an email in my inbox it wouldn't open. If I refreshed the page that often fixed it but kind of got annoying. Maybe I have too many other scripts running and they're clashing, I shall investigate further. Anyone else found this?

Thanks, it makes GMail look much better. Alex, how do you edit the script to add the css rules you mention (to hide the ads)?
