I especially wanted to customize one of these:
http://en.memory-alpha.org/wiki/Satarran - one of these:
http://en.memory-alpha.org/wiki/Night_Alien - and one of these:
http://en.memory-alpha.org/wiki/Wadi but I can't.
Ideally I'd like to see the character customizer eventually include features for every rubber-forehead alien in every series, but one step at a time. Can we see any additions soon?
