Thanks for reply. I will try to find that skin and put primo again on my phone even if I must say I didn't use it for a long time.
The point is that now we can visualize the historical traffic and make an idea of how heavy the traffic should be in a certain area, but with that option, to plan a route at a specific day/hour in advance, primo was able to give different alternative routes and a more precise view about the jurney. Example: I plan now a (let's say) 400 km route and nextgen says that it will take me about 4 hours to make it (real online traffic considered at the time I plan wednesday night), this allows me to plan some other things when I arrive, but after 3 days when I jump in the car and I make the jurney, the real time it took me to reach the destination could be even longer by an hour (leaving aside other unexpected events in traffic), hour which maybe could have been calculated involving historical traffic). So I cannot be at my destination the time I thought I would be .
