Here's a Google OS tab that contains some of the most popular Google gadgets grouped in three columns:
- navigation and search (links to the most important Google services and to your bookmarks, a gadget for searching the web)
- news (the top Google News and your feeds from Google Reader)
- communication (Gmail, Google Calendar, to-do items and Google Docs)
This tab remembers some of the changes I've made to the gadgets: I removed some Google services from the list of links, I added a custom section to the Google News gadget and disabled local search in Google Mini Search.
To share a tab, you need to click on the small arrow next to its name, select "Share this tab" and enter a list of friends. If you only want to get the URL that lets you share the tab, you can enter your email address. The changes aren't reflected in the iGoogle pages that contain your shared tab, so make sure everything is in the right place before sharing the gadgets.
