When I import a .DWG file to a Plan Drawing, it would be helpful if I could "dim" the background or selected layers so I could emphasize the Audiovisual symbols I am placing on the drawing.  Additionally, it would be really helpful if i could sort layers by layer name. 
‌While we are at it; why not enable layer visibility in the Current Layer Properties box.  This would save untold time on drawings with a large quantity of layers.

WORKFLOW:
I import a .DWG with 100+ layers (yes that actually happens). (I would be more than happy to send the mentioned .DWG file if it helps.)
‌When I click on an item in the Imported DWG (e.g. the Furniture) the Properties shows the layer of the current object. If i want to turn that layer off.  I have to remember the name, then go to the Layers, find the layer (why the sort by name would be helpful) and then turn it off.  
Then back to the drawing to select anther item I want to hide, and repeat the process.
I‌ spent over an hour doing this recently.
I‌f I could show/hide a layer just by clicking the light bulb in properties it would save a ton of time.

T‌hanks for listening.‌
