basic stuff to start out with

IK and FK hands. For the FK arms i'd like to visible rings around the joints (ie: shoulder, elbow and wrist)

For the body i'd like to have the lollipops for the chest, mid section and the waist. I'd also like rings around these areas as well in case for squash and stretch reasons.

for the waist I'd like to see a box for the COG (center of gravity)

For the neck and head i'd like it if i could have rings around both to be able to rotate them

For the clavicle... It's a little difficult because i'd like to keep it simple. Maybe some lollipops to do rotation and what not.
