Things I can disable don't make me grumpy. Just annoyed. :)

But I fully understand that it will most likely be off by default at release. Turning that on by default would be somewhat crazy. It's probably only going to be on-by-default for the beta period.. and that actually makes perfect sense, so as to expose more testers to it. More eyeballs, more opinions, more bugfixes.

But I'll still disable it on my own sites, so that I can never accidentally turn it back on. The nature of it as shown strikes me as extremely ill-conceived. Having things move around on my screen and making my screen actually become brighter overall is a lot more distracting, honestly.

I can kinda see doing a fade-to-dark on the non-focused areas, Sort of like how some video players on the web (like Hulu) support a "cinema" mode, where the rest of the screen goes dark and you only look at the brighter areas. That kinda works more to focus your attention on a specific portion of the screen. But scrolling the bar away, and fading to brighter colors (why must the rest screen be just so bright when nothing is there) is opposite of what I think is the intended experience. Staring into what is now essentially a light bulb doesn't help improve focus.
