The appearance is using one generic line for all taurs. But it is implied that exact appearance is based on the legs type. So if you have four feline legs you are cat-taur.
Hm... I actually like the idea, but someone has to write said descriptions.
Also, all scenes are written with a horse/leithan taurs in mind. Superior flexibility of other species? Nope. So non-taur scenes oftenly make more sense than taur ones for chakats.
Catnip. Use it on legs in...
I'd recommend STEP - the lore-friendly mods collection. It also uses own mod manager, which has some advantages, like much better handling of mod conflicts.
There already are three basic personalities, bimbo, and bro. While I like slut/sub stats in FoE, having them would require so many options to be written... And barely any writer bothers fully using what we already have.
