Try new GMail Navigation Menu

If you would like to try the new GMail Navigation Menu and you are not yet receiving the update you can force it by changing the content of the google cookie.
If you use Chrome, Firefox, Safari or Internet Explorer 8+, open google.com in a new tab, load Chrome’s JavaScript console (Ctrl+Shift+J), Firefox’s Web Console (Ctrl+Shift+K), Safari’s Web Inspector (how to do that?) or IE’s Developer Tools (press F12 and select the “console” tab) and paste the following code:

document.cookie=”PREF=ID=03fd476a699d6487:U=88e8716486ff1e5d:FF=0:LD=en:CR=2:TM=1322688084:LM=1322688085:S=McEsyvcXKMiVfGds; path=/; domain=.google.com”;window.location.reload();

Then press Enter and close the console. If you’re not in the US and you’re using a different Google domain, replace “.google.com” with your domain in the code (for example: “.google.co.uk” in the UK). Please note that this only works for the English interface, so you many need to adjust the language in the preferences page.
