Introducing Vessel - a desktop wallet for Steem

One thing I've always wanted was some sort of wallet to store my private keys in for Steem. Nearly every other blockchain project I'm interested has them, so I decided to take a some time and build one. I'm calling it Vessel, which can be a play on words for either "a vessel powered by steam" or "a vessel containing steam".This project - like everything in Steem - is experimental by nature, so please be diligent with your personal security and the safe backups of your keys in multiple locations. As beta software, there may be rare situations data is corrupted or wiped, so please use at your own risk and backup backup backup.With the advisories out of the way - please just be cautious. It's very likely that many bugs will need to be worked out.

v0.0.5 - Pre-release Alpha

This is the very first public pre-release of Vessel, which can be found here:

The newest releases will always be published via github, so please do not trust it from anywhere else. You can also compile it yourself from the source code, but I do not have instructions available yet. I will make them available as we get closer to a stable release.The initial features include...

A light wallet to manage your funds, your private keys never leave the wallet. Keys are stored within the application (with or without encryption, your choice), and only used to sign transactions. The transactions are then broadcast to the blockchain with your keys never being communicated outwards.
Importing of Private Keys. You can import an account by either using the login you'd use here on Steemit.com and specifying the permission level, or you can import WIF private keys using the account name and WIF.
Password locked accounts. Each account imported can be stored with AES encryption based on a password you provide. When used, each use of that key will require that password and your keys will never be stored locally unencrypted.
An updating overview of all accounts. The main panel of the wallet displays the total balance of all accounts within the wallet, as well as an individual breakdown of each account's balances. Hovering over a number will reveal it's true amount (if it's an extremely large number).
Claiming Rewards from your wallet. When your account has a pending reward, a section will appear at the top of the overview screen showing you how much and giving you the option to claim it.
Sending STEEM or SBD to any account or an exchange. The send screen lets you specify any account name to send to, or you can use the prefilled exchanges drop the dropdown to avoid mispellings and autocorrect. The available balance for the selected account will display for each currency, and when clicked on, will populate the field with the maximum amount.
Configurable Exchange Memos Enter your Bittrex or Poloniex memo keys for each currency and never have to go look those damn things up again. When you select an exchange during the send process, the memo will automatically fill with the appropriate memo for that exchange/currency combo.
Vesting - Managing Power Downs and Routing. The vesting screen shows the status of all active Power Down operations, allowing you to power down specific amounts, change the withdraw route, view the status of pending operations, and cancel any existing power downs.
Support for an unlimited number of accounts. Within the accounts section, you can add as many accounts as you'd like, each with their own set of permissions and password.
Setting Witness Proxies for each account. The second portion of the account page lets you set the Witness Proxy for your account, which is useful for those with many accounts or those who wish to delegate their vote.
