(caveat:) I understand that its likely avatars are a whole thing to roll out one day, and that what we have now is temporary.
That said, it would be great in the short term to have:
*-One long hair option for men.
*-One slightly historical/fantasy option for clothing for each gender. I'm thinking something really basic. A belted tunic or shirt over pants with simple leather shoes, or boots (into which the pants can be tucked).
*-Another attachment node or two for the head area
-A separate mode of walking that we can choose, where the left and right keys rotate the avatar instead of panning/walking in front.
-The ability to jump a little (correct me please if I just don't know how to do this)
-Ability to set a water layer at 0 that has a nice realistic shader. This way, islands will look awesome.
-Male and Female Avatars in Swim Suits (so that they can be tricked out with accessories without clothing underneath.
-Accessory attachment nodes on upper arms and upper legs (thigh).
-See through glass shaders.
-Sitting animation built into avatars.
-Simple dancing animation built into avatars.
-Ability to add a clickable node to a furniture mesh, such that when you click it, your avatar moves to the mesh, and sits where the node is.
