• Press Move and Hold Shift → Move the Node(without automatically align)
• Press the Node → Select the Node

Connection

• Press and Hold the Connector and move to another Connector → Create a new connection
• Hold Alt and Click Connection → Remove Connection
• DoubleClick Connection → Split the connection in the double-click position

Notice

1. ViewModelBase is for reference only, you don't need to use it, there are binding methods in Example's AXAML code.

Some known problems

1. Do not use Mode=OneWayToSource when you have multiple Nodify bound to the same ViewModel, this is a bug from Avalonia
