It would be nice to have expanded capacity without working too hard at it.

Yes, the app is pretty full-featured with tracking, waypoints, and auto-routing (add-on). Has satellite land views available and shows all docks. Depth contours are very accurate where I've checked and at 1' intervals (depths show at closer zoom levels). The some buoy representations are not ideal as they are more like ocean nav markers, but once you get used to them, it works ok. I use depth as a backup cross-check for navigation at night, using my depth sounder, so good depth readings are important. Phone brightness can be dimmed way down for night use.
