Universe Gizmos system allows for flexible setup of additional info displayed in Unity Editor
You can setup :
individual icon (any texture of your choice)
Label for displaying a name or a description of a GameObject
But Universe Gizmos are able to do much more! You can display on screen any info which you need for debugging your application.
There's a group of blocks Workflow->Gizmos->Gizmos Console for that purpose.
NOTE : Only for Editor.
