This would be cool if it were fast enough. The idea being that you could click a button on or off for a layer and it would allow you to see just the contents of that one layer while it was on. Layers are still quite slow compared to other softs that use layers, no doubt because of the amount of special data which is stored specific to the magic of AR. Turning off mutliple layers just to see the contents of one can take too much time as things are now. Just a thought.
