Looks beautiful. Miles ahead of the old GUI from a few years ago. I'll give this a try.
Questions: In the past I registered a premium account name on Bitshares. Will I be able to import my keys into the new wallet and preserve the account name? Do I start a new account by the same name and replace the keys in permissions?
It's still the same GUI/wallet so you can either just use your existing wallet or import your backup if you no longer have the wallet available in your browser.
