A suggestion
In the skin, in Saved Locations we have four options Home/Work/Other (exclude car) that can be defined and saved.
On selection lets say, HOME we still have to press Select as Destination and then Start Navidation for it wo work.
Cant it be simpler. When we press HOME/Work/Other, it just starts Navigation straightway.
Otherwise there is not much difference than selecting from option PLACES or HISTORY

Thanks
