This old tool
viewtopic.php?p=345385#p345385 adds a piece of text on screen with the scene's name and puts it on a new layer named after the scene that is only 'on' in that scene and by default it is never 'on' in new scenes made later.
You can use it to add that scene specific layer and the screen-text if you want it.
To do it en mass use the ALL version or on the active scene...
This massaged version misses out the text and just adds the layer...
AddSceneLayers.rb
Note that you can edit the code to change the new layers' prefix, which by default is 'SCENE-' so that they all list together
