I don't mind breeding, but maybe a few other things.

* More barding

* Skill point respec

* Feather dyes

* Single player + chocobo and/or two player + two chocobo dungeon instances

* Chocobo carriages, allowing transportation of multiple people on a single transport and maybe add a mobile access point to the company chest.

* Allow chocobos in cities, at least in Companion mode

* Let us have a minion out when our Chocobo is in Companion mode (I want a pic of me my new Mog minion and Choco all together)

* Chocobo emotes for them and us (like petting)
