Add a parameter to ShowVariableViewer() to display nested elements directly.

[Kurzer]

If you want to view a deep layer in a highly nested, structured map/array/list with the variable viewer, you have to work your way to the respective element with several mouse clicks each time.

Here it would be great, if you could give the command ShowVariableViewer() the desired element as a parameter, so that the corresponding entry in the structure is displayed immediately.
