Can this use the default bitcoin wallet or does it create its own? I have the main Bitcoin app (which takes up almost 20GB on my SSD with it's blockchain) and I have a few others, like multibit. There doesn't appear to be any wallet management, each app creates its own wallet and can't open the wallet from another BTC app.
