I often find myself planning trips, and it is important to set final destination back to home to discover need for charging during trip. So it would be nice to easily set final destination back to home.
Also for longer trips, perhaps add possibility to set parking in hours so ABPR can calculate vampire drain to fully plan charging on longer trips w limited charging opportunities on some destinations
