If the Windows 8 + IE 10 + touch user agent is something we can detect, we can force it to switch the theme to the pfSense one.
If you'd like to see those features in a theme, you're more than welcome to make a theme, offer a bounty to make one, or search around and find if someone has already made one that works like you want.
IE barely functions with our GUI anyhow. Get a different browser ASAP. ;D
