Having used MSE with the new theme, there's a few things our users are probably going to love. I currently use it in desktop view on my phone, and it just works, and as a mod, this is a very nice thing (The current theme is usable but less so).

I'd ask you guys consider a black on white banner,  more in line with the current theme (which lets us keep our bicoloured logo), but I'm sure you guys have good reasons for the current theme option.

Other than that, and a few universal requests, I think it looks good.
