A few ideas about hitching/titling/mounting:
1. Autohitch. When you mount X, you also hitch X (if possible). 'If possible' because sometimes you will have already hitched two mounts other than the one you are mounted upon.
2. No-Argument Title. The title command without a target or argument, titles the mount you are on.
3. Automount. When you rent X, you automatically mount it (if not already mounted).
4. No-rent hitched. If a mount is hitched to someone (yourself included), you can't rent it. Alternative: if a mount is hitched to someone else, you can't rent it.
5. Hitched Command. 'hitch' without argument would list off which mounts are hitched to you. (I could see a 'follow' command without argument listing off who was following you too as useful.)
What would this solve?
1. Newbie confusions about hitching. So, says the newbie, I have to both mount and hitch this mount?
2. Multiple mounts. You go to the stable, hop on your war beetle, and someone else comes in with a war beetle, and so you have to 'hitch 2.war', and if there are many, it takes a while to figure it out. So too with the 'title' command.
3. Crashes/logging out. If you log out and a mount is hitched to you, it logs out with you. If you forget to hitch, though, then it won't. Likewise (maybe) with crashes: if it is hitched to you, it'll not get lost in a crash. (I'm not sure about the latter.)
Anyway, super minor.
