Spaces & Expose in Mac OS X 10.5.3

As explained by John Gruber, Apple has improved Spaces support in Mac OS X 10.5.3 but there are still some broken features.

When I'm reordering my windows, instinctively, I want to activate Spaces then use Expose All Windows feature to rearrange them. But this does not work: I have to first use Expose then Spaces.

Before 10.5.3, it was not possible to use Expose when Spaces was active. Now, we can activate Spaces and then display All Windows in Expose using the screen corners or the keyboard's function keys:

However it still does not work using mouse keys.
As for Expose Application Windows, it does not work at all when activating Spaces.

The behaviour I'm expecting from Spaces & Expose is to be able to switch between Expose features (All Windows and Application Windows) and Spaces in any order using either screen corners, function keys or mouse keys.

Maybe I'll have this behaviour in Snow Leopard...
