what's missing in blendlist

during runtime: selected camera

in the inspector, without showing debug text

Noted. You can make it yourself by attaching a custom behaviour to the BlendList that polls BlendList.LiveChild and displays the result in the inspector.

off course i can write all sorts of things to fix what’s missing in the editor, makes project heavier with more plumbing
