Here is one simple idea... at least I think it's simple idea. If you could make an option in character creation for Khajiits to give them different stripes and spots all over the body and being able to change color of stripes. I'm kinda annoyed that my character has tiger like face and neck while the rest of the body is stripe-less or spotless.
Hehe... while I was writing that I remembered that there is only one armor which is upper body uncovered. So it would be nice if there would be few versions of normal pants with different colors and one armored version of pants (similar to dark brotherhood armor just black and with boots).
lol i just have chain of ideas... sorry here is another one. A Barber shop and of course it would be payable service! Or for free some place in your home where you would have an option to only change your hair style, facial hair and facial markings. But you would need to obtain a home before that.
(I just created new character which is imperial, and It would be nice that as story-line goes my character is changing)
Ok now I'm done.
