I have had 2 megapoints boards and a mega panel sat here for about 3 months. so in the last few days finally got round to setting it all up. like has been mentioned above once you get use to the button pressing travel of the points can be set in seconds. the panel with some addition gives a full mimic of the layout with a single push button for changing the points both ways.
as for unused outputs with a bit of building and thought you can use them for crossing barriers uncoupling ramps. I have even set up a servo up in the garage on a car ramp. just waiting for my linear servo's to arrive to see if a loco lift is possible.
