This, please! It's the single biggest change I'd personally like to see added to the uniform options. As an exclusively Caitian player, I'd jump at the chance to have the bare-pawed look similar to M'Ress with my uniforms and bridge officers. :)
I don't suppose that since you're going to be adjusting footwear, you could possibly add in the option to use the Caitian bare feet/paws with uniforms while you're at it? Pretty please? :)
