Smart Route Planner is anything but, it's actually a terrible app
The cryptic use of a pencil symbol to the right of the leave now text, is far from intuitive when it comes to changing the start or arrive time.
What's the point in giving me the option to go via somewhere, if you don't give me an easy way to pause my journey? Who diverts off route for the sake of it, without stopping?
I've had to start my journey go via a location, continue on to my destination and then add time mentally to the arrival time shown, to allow for the stop I need to make, so that I know what time to actually leave! Fine for route planning maybe, but useless for journey planning.
