It still boggles the mind that the so-called "sliders" that others on this forum have referred to could not be implemented.
+1 I really hope they consider adding the option - even if it's with some free update after release. Small changes that wouldn't change the head geometry too much (and wouldn't affect head animations) can be used for great effect. Here's an example: Before & After: just 4% size increase and 8% rotation
The 'after' pic was elven enough to fit in with BG2's Aerie, Viconia (and Jaheira) just fine. (sidenote: both images had the head lowered by approx 2 vertebrae. Also... we really need to get rid of those extra vertebrae. These aren't D:OS2 elves!)
