I really miss layers. So much that I have learned a little bit of coding to allow the required functionality similar to Rhino, for example.
The best layer addons i have found are
vtools_objectsLayerManager.py - as it has good ui, and you can quickly hide and unhide multiple layers
super_grouper.py - the hiding hack implementation of placing objects in a temporary different scene is great as it is independent form the objects outliner visibility (“h”/“alt” + “h”), and render visibility
So I have forked objectsLayerManager, and modified the code as in super_grouper to place objects not visible in a temp different scene.

Happy to hear feadback and suggestions
