In the current implementation of hierarchy and breadcrumb Node are identified with their class name. when the scene tree is very deep, hierarchy and breadcrumb are difficult to read.

eg for hierarchy :
Hbox
->VBox
-->HBox
--->HBox
---->Vbox
----->HBox
------>textfield

eg for breadcrum:
HBox>VBox>HBox>HBox>VBox>HBox>HBox>VBox>HBox>Textfield

What if the Node Id was displayed additionnaly to the class name at least in the hierarchy like this ?
Hbox - MainPanel
->VBox - CenterPanel
-->HBox - CenterTitle
--->HBox - CenterMainZone
---->Vbox - CenterBottomZone
----->HBox - etc
------>textfield - mySuperField

a similar display could also be done in the breadcrumb:
HBox > VBox
MainPanel > CenterPanel
