Get node - focus on it's Set node on double click

When working with complex shaders, Get/Set node approach becomes hard to read and hard to find where the variable was Set.

Having some way to "focus" or "zoom on" the Set node, when you double click on its Get node of that variable could help a lot.

Additionally having an option to highlight all Get nodes, that are using the variable set in Set node would be great as well. For example in right click context menu of both Set node and Get node.
