I wonder why Google isn't offering a DOM Storage implementation of this. Versions of Firefox 2 and later offer built-in support for WHATWG's DOM Storage API, which would (theoretically) allow users to have this functionality without installing the Gears extension. My best guess is that Gears is more robust and probably easier to implement things with than DOM Storage, but I'd appreciate if anyone with experience using both could confirm this.
