I'd really like this made easier too, so I filed an enhancement

Is it possible to file a de-enhancement request? ;-)
Am I the only one mystified by the attraction of this particular
effect? It burns CPU/GPU time like there's no tomorrow for no apparent
benefit to the usability of the UI. The original idea of semi-
transparent windows seems a good one - you can still read some of the
content behind which can enhance usability when you need a quick
reminder of what's there without having to activate the window. For
example there are times when you have no choice but to retype
something you can see in one window and enter it in a field in another
(admittedly these times have got a lot rarer with static text being
often selectable/copyable, but it still happens).
With blurring, the ability to do that has been wiped out in a lot of
cases. Why? What's the metaphor for a blurring window? Frosted glass?
How many windows in the real world use frosted glass? Not many in
proportion to transparent glass, that's for sure. When I first saw
Vista I chuckled at the widespread use of the blurring effect because
it seemed like those guys had introduced some gratuitous eye-candy
without getting in any way why they'd done it. I was sorry to see that
the joke was on us in Leopard. Leopard's blurring is subtler than
Vista's, so let's be grateful for small mercies - but I do think we
ought to be debating why we have this at all.
A public API for this would mean that every man and his dog will be
adding blurring because it's "cool" without thinking about what it
*means*. It's going to be the brushed metal of the next few OS revs I
fear.
Just my 2ยข worth...
