I like the idea that you can take an existing huge and complex app,
plug this on, navigating and track down the bottlenecks in rendering
without even knowing how the app was built.
For bottlenecks in other phases, I guess the tree representation is
less eye candy but more usefull, showing all the RR phases with
execution times and sql, right ?!

On the other hand... 99.99999 % of the time the other phases will
spend all the time in the someAction() that is bound to a button or
a form... so having the button you just clicked on colored in red
won't be too helpfull, will it? But you could hack that by rendering
the current page and stuff it in thread storage or some dict or
other. Then you could show it later on on the click of a button.

I'm still not completely satisfied with this concept ... It really
depends on what kinds of problems you have on your page, but the
main issue with it is that you can only really visualize the
appendToResponse phase, because the takeValues/invokeAction are
often for the previous page. So if you're on a page that's
expensive to render, this is useful, but if you are diagnosing a
problem in another phase, this won't be all that helpful. However,
the profiler shows you the % cost of each phase, so you can use
that to judge whether you want to focus on heatmap.

I've just taken a look to the documentation, that seems just
impressive... I mean :
"Once you turn on heat maps, future requests will have colored
boxes drawn around expensive areas of the page. The closer the
border colors on your page are to red, the more expensive they
were."
That's just brilliant, can't wait to experiment this.
Thanks Mike and overlords :)

Bah ... sorry. link to our internal build server. THAT'S not
gonna work.
