I use Modrana not in the least for its tracklogging options.
I cruised Israel by touring car and Modrana was perfectly usable to orientate and make tracklogs to keep a journal to match the photos I shot. In some films I shot I just aimed at my screenie now and then. I'm from the Nether lands so I was positively surprised that it did log the altitudes so well (Dead sea f.i. is 400 meters below sea level).

I like hiking and sailing.
While I use Modrana with Virtual Earth sat map for all navigation purposes I have a bulky Tomtom too. Sometimes in the car I use both --> Modrana for the photo-artistic side more or less zoomed out. On my Tomtom I have Offroad navigator installed and that has a function I would much like on Modrana as well: absolute directions for next waypoint. If it could show the angle to the next waypoint you would be able to make accurate decisions at sea (where you not only evaluate the absolute angle, but also stream, wind etc). Cumulus has this option but I much prefer Modrana UI.
