Global Editor
Global Editor is an editor window which provides access to all of the available asset settings (excluding scene-dependent ones) in one place. There you can configure game settings, units, productions, factions, texts, abilities, etc.
You can access it from the Top menu -> RTS Starter Kit -> Global Editor.
You can also open these editor windows separately from the same menu.
Note
