Track pad users may want scroll to be scrolling....

So consider that,  although I rarely edit layouts by trackpad there are times that I do and hate zooming in and out.  But when using a mouse I do want zoom in and out on the scroll wheel.

If your toolkit allows for the apple trackpad gestures...  That could add a few options into the mix



In net mode double left click ends the current net.

You added net end, but starting at the middle of a net segment is valuable too.
