Is there a place to submit a feature request? Why is there no ability to manually adjust the headrest position? I know it adjusts on it's own based on how far back the seat is, but I prefer to fine tune it. Also, recently my headrest is feeling very hard after a couple thousand miles since new (like it's lost it's cushioning). Has anyone else noticed this? It's starting to feel like my head is laying on a rock. Also the super cheap belt buckles are starting to annoy me - the metal is exposed on one side and they feel flimsy in the hand. Can the be replaced with something nicer?
