Clone a node
Add the ability to clone a node, like you can do in e.g. Nuke. From Nuke's documentation:
"You can clone nodes in preparation for pasting them elsewhere in a script. Cloned nodes inherit the values of their parent, but unlike copied nodes, they also maintain an active link with their parents’ values. If you alter the values of one, the other automatically inherits these changes.
Clones are helpful for maintaining consistent setups across multiple elements. For example, you might use clones to apply an identical film grain setup to a series of elements shot on the same stock. Should you need later to make changes to the setup, these changes would automatically ripple throughout the script."
This can be achieved in Designer through exposed parameters, but that's pretty cumbersome when nodes have many parameters, and you also clutter the graph's input-parameters with variables you actually only want to use internally, not expose to the user.
Cloning a node would set this up automatically.
