Collapse Top Navbar and Searchbar from Google Calendar

In my previous post I ranted about the UI space wasted in Google's pages. So I thought to do something about it.

Here is my first attempt where I remove the top navbar and searchbar from Google Calendar's page. I hardly use them and I suppose this is same with many users as well. Instead of these a small button on top left is shown which toggles the display of these items.

This is a Greasemonkey / Scriptish script. It is available at:

Update 1: Sometimes the G+ profile info box may appear out of place. Refresh the page and it solves the problem.
