Done downloading the wallet, but it is out of sync, do you have a working node for this wallet, I only got 1 active connection..
Anyway...
This project look interesting...
Yes you can sync your wallet as soon as it finds a block, it happens automatically.
If you are connected to another wallet as you describe in your message this will soon synchronize.
You can also start mining a few blocks directly in your wallet, mining in "bet" mode you just need to encrypt it and follow these steps:
Go to Help.
Click Debug Window.
This is the console where you will execute all commands.
Type this command to start staking:
walletpassphrase REPLACE_WITH_YOUR_PASSWORD 8888888 true
Replace the text "REPLACE_WITH_YOUR_PASSWORD" with your password.
We are happy for your interest in our project.
Thanks for the questions.
