In practice, there are usually hundreds of actors in a level and each actor could have tens of properties, it is painful to set/get actor's property, you need firstly to locate the actor in outliner and then have to switch to the detail panel to search for the right component and then the right property to check or modify. Besides, as a programmer, I always prefer keyboard than mouse, so I wrote this plugin to enhance the console command line to support to get/set scene actor's properties with certain level of intellisense.
Since this plugin enables you to modify most of the actors' properties via console command line, I call it Zillion Command Query.
