I am not sure when they launched this nifty feature, but the customizable Google Homepage (http://www.google.com/ig) now has a nifty tabs feature that lets you add multiple tabs, rename the tabs, and drag content between tabs. For those of you like myself that have far too many feeds to keep track of you can now separate similarly themed content and just switch tabs.
The best part? It remembers which tab you were last one and loads you up to that one when you re-visit the page or refresh. Awesome job Google. This definitely makes me happy.
The only downside? Tabs cannot be rearranged. Create new tabs with care and in order.
