Pinco's UI will be the one you want. I have released a Copper Theme and Third Dawn Theme that works with Pinco's UI (though one or the other, if you want to try both, install Pinco's then copy a version to a separate folder so you have one for Copper Pinco and one for Third Dawn Pinco) that are downloadable at Pinco's site. Both are functional with the current version of Pinco's UI.
