I havn't seen a place to input "home" coordinates, but I have noticed that by double-clicking anywhere on the map (any version, topo, aerial, quick, or scanned) the rest of the caches' distance is recalculated to that point. I like that feature, but it would also be nice to have default home coordinates listed in the preferences somewhere for everytime you initially open the software and perhaps a button to reset it back to home after you are done using the double-click feature.
I agree, I also like to be able to sort by distance
