How can I open or refresh the config dialog so that it selects a specific node in the options tree?
I believe you need something like this if you make "dynamic" options where the result of a change in the options by the user changes parts of the options tree. A simple example would be a tree group where you have an input element to change the name of the current node. You will then want to change the options tree and reselect the current node (which will now be at a different place in the options tree). Other examples include adding nodes where you will want to select the newly created node.
