Since 8.0 will be bringing an expanded character creator, lets share some different options we'd like to see and customization options that have been long requested since day 1. I'll start:

All races:
  • Base skin textures, including plain, blushed, freckled, and body hair styles for skin.
  • An "Age" slider ranging from youthful to aged. This would add visible aging/wrinkles to the character's skin and face, through a normal map texture layer.
  • Muscles available for all. Add the muscle normal map to every race and gender(yes even if someone wants to be a silly muscled Lalafell!)
  • A tattoo layer, where you can earn different tattoo styles to put over your body. This would apply over the base skin layer similar to the legacy mark but on the full body.
  • Body shapes: standard, thin, muscular, chubby. Just basic skeleton morphs to give players more variety.
  • Add more faces, and make all the facial options such as scars, makeup, and other things usable between every race and gender. I want a scar on my Lalafell's face!
  • Add more robust beard options to every race. I'm aware the bearded look isn't very popular in Japan, but many western players like to have beards on their characters.
  • An option to change the base animation set on characters so that your personality isn't locked to your race+gender choice. For example, a lot of Hrothgar players want to have less hunched over animations, and many Lalafell players want to have less silly/joke emotes. Let players choose how their character's personality is like.
Hyurs
  • Eyebrows for male Highlanders is a big one that people have been asking for for a long time.
Miqo'te
  • Add options for different ear styles (you can easily allow Miqo'te to feel like a different race by allowing a wide range of variety of different tail and ear options)
  • Tribal mark options/layouts. Maybe let you edit the color?
  • More tail options, and perhaps increase the poly count on them since they are a bit flat.
Aura
  • Let you choose horns individually from the face.
  • Allow players to change the colors of the tail, horns, and scales.

I probably missed some of the stuff that have high demand, so please share any additional options you'd like to see added!
