Well thank you for your response. I am not expecting anyone to do r&d for free, I am only going to as many retailers, rental places, and visit as many forums as possible to get inside the head of the user. Engineers care about how things work, yes. But at the end of the day they will sacrifice user experience for cost any day. I don't expect to fix something that many of the larger companies have failed at doing already, but looking for gaps where design has failed to meet user needs that until this point they have not even realized they have. Thank you though
