I don't how how feasible this is, but it would be really nice if you are able to dismount from your chocobo and maybe have like a set time before it would run off(wouldn't want to have riderless chocobos all over the place) so that you can freely walk around or go turn in local leves, do quests and/or kill mobs and be able to hop back on again and be on your way. Just an idea.
