This plugin allows you to extend a child network by adding the neighbors of a selected node in the parent network. This can be useful when you have a large, complex network and you want to focus in on some portion of it. For example, if you create a child network of p53 interaction partners from a larger network of all Human protein-protein interactions. If you find an interesting interaction partner to p53, and want to see its interaction partners, you can select the partner in the child network and select Plugins→Add neighbors from parent to add all of the interaction partners of that node in the parent network to this network.
