It would be a nice to have feature if you have an auto walk feature. This is what I was imagining it. Open the world map and then select a town you wish to travel to and then you select autowalk button. This will make you character start walking to that town from where you are. The auto walk feature makes the character on main roads only and it would not go directly from point a to point b.
This feature will only work if you are standing on the road.
Sometimes there are animals in the way which attacks you. This cancels autowalk feature if you are seriously hurt or interrupted.
Right now because you are traveling so much it gets kind of boring. This will at least make it little faster as you can focus on other things like chatting etc.
