[GPSNavX]

I have an idea. I could reuse the [^] button on the MacENC toolbar to scroll to the "home" waypoint IF there is no GPS connected (i.e connect on the "GPS" menu). Normally this button is used to tell MacENC to scroll the chart back to the GPS position. Let me know if that would work for you. Because of the limited screen real-estate Mac laptops have I really try to limit filling the screen up with one trick pony buttons. Instead choosing to maximize the screen for the chart. This is contrary to just about every other MS Windows marine navigation application that seems to take up every edge of the chart with buttons.
