These userscripts are always flimsy and break whenever their intended target site changes their code. Also, nobody seems to make any reviews saying what's working and what's not that much on Userscripts. This leads to installing and testing A LOT of unnecessary scripts. To break the habit, I will review this script.

I'm glad to announce that this script works as of Saturday Aug 8, 2009. You can see a text link at the very center top that lets you toggle hiding the left sidebar/panel of google calendar. Still works after 3 years, damn...

How hard is that?
