My feedback: I wish it was -15 °C... To snuggle up under a bundle of blankets sounds divine. Instead, it's almost midnight where I am and it's still bloody 32 °C.

The UI looks nice, though I've effectively disabled the Overview and replaced it with the ArcMenu on my setup. I've also aligned my common/active applications to the left on my panel rather than centred (so that my pinned applications are always in the same position and don't budge over when I open another program). Rounded corners doesn't do it for me, I try to avoid anything that removes screen real-estate, no matter how minimal. I've also set the bottom panel to auto hide so that it's only visible when I move my cursor at the bottom of the screen. Overall, your setup's pretty nice, though I don't think I like the bright colours for the buttons in the top right of your windows, they're a little distracting. Mine's set so the cross is a washed out red colour, the minimise button is a pale horizontal line, and I don't have a maximise button.

I'm going to install that Weather or Not extension. Thanks.
