Tangentially to this, here's a random tip. I really wanted to be able to use mounts besides my chocobo, I wanted to be able to ride my chocobo when she was out, and I wanted to be able to have only one button to press to ride a mount regardless of the mount/gearset. Before 2.3, you couldn't do this, but now you can, since you can now macro mounting. I have macros like this:

/micon "Cavalry Elbst" mount
/mount "Cavalry Elbst"
/mount "Company Chocobo"

For each of my cool mounts. Then, for different classes, I put different of the macros in the slot for the button I want to be my mount button (F12). This way, I can always ride a mount by pressing F12 (chocobo if he's out, something else otherwise), and I can tailor the non-chocobo mount to whatever class I'm being (Elbst for FSH, Gooboo for BTN, Unicorn for SCH/WHM, Magitek for BLM, etc). Now I don't have to think when my chocobo is out about which button to press to mount up :P
