I like it. One thing I would add though is the ability to display your receiving address as a QR code, since I generally use my phone for BTC transactions.

The way you hash passwords is wrong, and worst by someone involved in bitcoin. var passwordDigest = Crypto.SHA256( $scope.password )

Thanks for the feedback. We're following https://code.google.com/p/crypto-js/#SHA-2

Could you let us know how it's incorrect? Otherwise, feel free to make a pull request on https://github.com/BitcoinMafia/SpareCoinsExt

You should suspend your project until you understand enough crypto to implement a cryptocurrency wallet. Follow the cryptocat project to understand the risk you are facing.

So how does this actually work? The private keys are stored offline?

Your encrypted private keys are stored in Chrome Storage, they are encrypted via your password digest so your password is never stored.
