This Node is similar like the Name-Node. Instead of writing the Name in the Node Infos, you can select the Name from a Popup, wich maybe is a little bit more comfortable. Using the Name input is often used by myself for quick testing, debugging or Stand-alone Scripts. This node helps eliminating errors like writing the name on the wrong field or copy/paste the name on wrong place etc.
A new innovation implemented, is a visual feedback of the node, which zooms the named object while choosing it in the popup. Which is a very interesting advance to improve user friendliness of Marionette nodes.
Ideas for further improvements:
1. Checkbox if zoom or not (not sure, because to many checkboxes decreases usability)
2. A Pick option to pick an object and auto-naming and inputting with this picked object (Not implemented, because I have not got it to work, that a pick callback runs inside of a Marionette script)
