Here's a list of my suggestions. I will update it when/if I think of more.

-Linkshell re-arranging abilityThis is a really annoying issue for me and others I imagine. I like to have my things neat and orderly to better remember/find them and Linkshells are one of the things incapable of having that way. If I wanted to re-arrange them I would have to do it in the obnoxious manner of deleting and rejoining again. There has to be a more efficient way of doing it.

-Hairstyle Swaps When 2.1 came the first thing I was jumping for joy about was the aesthetician. But once I got into the hairstyle options I was very disappointed. All the other races had received new hairs or hairs from another race. But Hyur's didn't. I was looking forward to the idea of being able to use other race's hairstyles. I wanted the Miq'ote's ponytail so badly! I really think ALL hairstyles should be available for ALL races...
