There is more coming.  Getting it just took a much longer time to happen because Earthcoin supports transaction messaging (meaning there is an extra field in the blockchain).  Getting the two way serialization and the protobufs to work properly on Android too a MUCH longer time to work and we believe we will be the first android wallet to support transaction messages.  You can look at the devs' previous work.  Our wallet was developed by Xploited and HashEngineering.  Take a look at the wallets they have done previously (just use bitcointalk search) you can see that they have developed wallets in shorter time periods for other coins. Getting Earthcoin to work for Android was no simple clone.  Also, there are more features, but we just gave you a screenshot of a successful transaction.  The serialization and protobufs were what was holding up development, but the screenshot you saw is not the wallet as it is being released.  Now that it is finally functional, the other unique features are being built into it.
