How do I determine the layer of an object if it's on a layer that is locked and I can't select it?
I tend to use dozens of layers in my drawings. For security I only unlock the ones I'm working so I don't move the wrong object. To determine the layer of an object, I sometimes have to unlock all, select the object, move it to where I want it and then re-lock the layers I want locked and carry on. That wastes a lot of time.
