Multiple linkshells suggestion.

Actually lets go with both, but prioritize the /ls(n) chat shortcut. I can stand behind the /el (n) command because it would be a great complement to the /ls(n) shortcut, but the chat shortcut is what most people need/want the most. It should even be shortened further.

/l <text> Talk to current equipped ls
/l1 <text> Talk to ls #1
/l2 <text> Talk to ls #2
/l(n) <text> Talk to ls #n

/el (n) Equip linkshell n
