I don't think it's necessary to add the extra variables to make the code readable. Just split the lines where it makes sense. That should be enough.

OutputImage(file, allFaces.Where(f =>
f.Proportion > double.Parse(ConfigurationManager.AppSettings["LowerBound"].ToString()) &&
f.Proportion < double.Parse(ConfigurationManager.AppSettings["UpperBound"].ToString())).ToList()
.OrderBy(f => f.Proportion)
.ThenByDescending(f => f.Rectangle.Height)
.FirstOrDefault());

I think you should try the Firefox tab management before jumping to conclusions. I use it everyday, having my tabs arranged by my various projects. All it takes is 2 clicks to swap between sets of tabs. Setting it up couldn't be easier. Click the Group Tab button, double click and now you're in a new tab group. To swap to another, click the button and choose which group to load. I seriously doubt you're going to find anything easier or more useful for managing tabs right now. I too keep on the lookout for time saving ways to manage tabs etc and this really is the best thing out there that I've come across. You can try an extension called 'Tab Sugar' for Chrome, which is supposed to do the same thing, but it was buggy the last time I tried it. I hope this works out for you. If not, please post if you find something better.

Almost everything you ran before will run on the desktop in Windows 8. If you haven't downloaded the developer preview, it can answer a lot of questions for you. Win8 has basically 2 layers. One is the Metro theme with it's apps and the other is the standard desktop. They both work hand in hand for you to do your normal whatever. The Metro theme is basically a pretty app launcher and the desktop is the same old desktop with ribbon elements for the windows, an up arrow for explorer, and the start menu removed. While the Metro UI will launch apps, it can also launch desktop apps as well. When I installed Firefox, it placed an app launcher on the Metro UI as well etc. When it launches the desktop app, it switches to the desktop to load it. It's unfair to say that the desktop and it's apps are 'shoved aside' in place of the new Metro UI because you end up spending a considerable amount of time on the desktop anyway. Sure, once more and more apps become available, you'll be spending more time playing with them, but when it first launches, you'll still be using the same old apps. Even with all of the new apps, you'll still be spending considerable amounts of time on the desktop as it's the only way to move files etc. Overall, both UI's work together and it's all a buttery smooth process once you learn to use the little UI swapper.(No idea what it's called) Basically you can use that and the windows key to go back to the Metro UI from the desktop. I plan on spending some additional time with it, but for the first few hours of using it, I really enjoyed it. The only things I didn't like were the removal of Flash and Silverlight from the Metro IE and the removal of the standard Start Menu for the desktop. Even with those, I can say I'm looking forward to using this. The UI was quick and snappy. At no time did I ever feel it bogged down or get that 'boated' feeling. Oh, and one note to backwards compatibility.. I tested a vb6 game I wrote about 10 years ago and it ran exactly as you would expect.
