yes, you can manipulate BCC and BTC from same application, migration is not supported but yes, you can use import/exportIn the examples shown, it has support for creating a new BCC wallet and working with BCC transactions.
But what about existing BTC wallets? Now that the fork is done, would the procedure be to import from the backup 12 word phrase but with BCC set to get the duplicated funds on the BCC chain? Could this be automated in the UI somehow?
Sidenote: I'd suggest a different icon to differentiate BTC and BCC wallets in app.
its only alpha and have no skin yet.
