I dont line comparing to unity etc.
But I know in Unity there is a hierachy (tree) where you can see all entities incl the spawned/cloned ones via script.
There you can see all entities as a tree with childs etc. Very helpfull I think to have an overview. Also good for debugging or if a game starts laging. Otherwise you maybe never find. Also nice would be if there would be the memory usage for each. Very helpful IMO.
