Expose is great and all. Really great. I love being able to easily get at files on my desktop, without having to either move all my windows, or hide every application. Both of these are easy operations, yes, but hitting F12 beats it hands down.

However, I think a cool feature would be this: pushing the frontmost application (and only the frontmost application's) windows out of the way.

Just now it happened - I was reading some instructions that told me to move a file (or a bunch of files) from location X to location Y. I open up two finder windows, and now I don't have screen space to read the instructions. Isn't this one of the problems Expose is trying to solve?

However, I have great hope for Expose in 10.4. In 10.3 it was a 1.0 release - I'm sure that engineers at Apple aren't finished building features into this killer app.

I just discovered something very very cool.

Just now my sister asked for an email address of someone. I have the address in my Address Book, so I fire it up, locate the person, and think about copying/pasting the email address.

Instead of doing that, I drag the address card to my iChat window. iChat wants to transfer the address, as a (vcard) file, to my sister. Great. I send it. She double clicks on it at her end, and the address card is added to her Address Book.

This just all made inituative sense. It started with a "Hey, I wonder...", and turned into a timesaving trick ('cause there's a lot more information on that vCard then just the requested email address).

Yay for Macs.
