The app is a toolkit to perform many actions on the EOS Blockchain.
It allows the user to import an existing account (private key) which will be encrypted and stored securely in a local vault.
The toolkit will list the account balance and resources (staked vs unstated, RAM, CPU, NET) and list the balance of all tokens.
Through the simple UI the user can perform staking and unstaking actions, buy or sell RAM, vote and set a proxy and transfer EOS or any other token to other accounts.
The history view lists transfer actions (in and out).
