It may be possible to add, when you're working on a polyline, the command layer on / off?
I make this request because when you're working on polylines, you are forced to think, before you make a operation to turn off or turn on the command that you find on show / hide layers, which, moreover, is not independent of the other normal operations of edits such as delete, copy, move, etc.. So for example, if you, in another previous operation had turned off a layer to delete a line, when you go to edit an existing polyline (move, delete, add a vertex), you have to go back twice to turn on or turn off the layer that interests you and then go back to edit the polyline.
