1. Personal housing (i.e. like moogle house in ffxi) can decorate, garden, gain extra resting xp sleeping there before loging out, Have armor stands to display your best armor/weapons, fish tanks, etc etc

2. Thank you for the ability to color chocobos, great idea useing food. how about food or something like that to alter appearance (i.e. larger beak, bigger, smaller, things like that)

3. Another chocobo idea, armor, weapons, stats, quests, just like your main character. You get X armor and your chocobo's defense goes up. Just to clarify im not talking about barding that looks great but does nothing stat wise, im talking about craft-able armor, weapons, to improve stats.

4. Referring to Item #2 food to change appearance, when you choose bigger legs or whatever, there is a speed or jumping increase or sharper beak, there is a dmg increase. that way in time there can be events where you can do chocobo races/obstacle courses, pit your chocobo against monsters in the pit.
