I know that it doesn't make sense to necessarily to have the ability to adjust the walking line direction because going up will always be up....but can you change the walking direction so that down is really pointing down the slope of the stairs? It seems reasonable yet philosophical too: who really wants to go down the stairs...some do...some only want to go up the stairs.
