Watched the new demo and it's so exciting! Amazing flexibility and variety... and the possibility of 'accidental monstrosities'.
So, I'd like to suggest the addition of Numeric input on those sliders.
That would allow us to have easily repeatable presets and shortcuts to a desired look. It's an issue I've seen with character creators in other games, as well. If one lacks hand-eye coordination, or precise control of the computer-pointer, it can be very difficult to nudge a slider just the right distance to get the desired effect. Also, one can't, reliably, put the slider back to 'neutral' or 'zero', or any other target.
These numbers don't need to correspond to any measuring system, they could be percentages on the slider's scale, or completely random - as long as they're repeatable.
