Heroes VII

Does anyone have any suggestions for the developers regarding caravans? I suggest giving the hero the ability to "hide" in their caravan. And it would be nice if they added a travel spell, like "snowstorm," that would cover the road in snow in a certain (small) area of the map, making it difficult for the enemy to move for a day or two. I think they are unlikely to want to implement the second suggestion (as well as the first), but who knows...
