I love brilliant little freeware apps like this. That said, I question the entire idea of Expose on a Windows box. To my jaundiced eye, Expose is an innovative solution to the problem of not being able to switch between windows within the same program easily on a Mac. In Windows, each IE window for example, is its own item on the taskbar whereas on the Mac, all of the IE windows are a single item on the dock. Alt+Tab on Windows can cycle you though all the open IE windows, but the same operation on a Mac will send focus to the next app, not the next window. I currently have 10 IE windows open and at a single click I can see the titles of all 10. The “intelligent” taskbar in Windows works extremely well for something of this nature.
The other problem I have is that several of the business apps I have open (SQL Enterprise manager, GroupWise, Explorer in details view and Dreamweaver) look pretty similar - if not identical - in thumbnail view. I shouldn’t have to roll my mouse over everything to figure out what it is. I can just click the icon on the taskbar. None of the icons look the same. This might be more practically useful if I used just browsers or graphics apps. That said, it’s much more practically useful than Sun’s unique attempt at 3D window managment .
If it handled my iTunes plugins and Yz Shadow better, I might add this to my ever-growing stable of very cool but ultimately useless “chrome” apps. At the very least it would tick off my Mac buddies by co-opting their Mac OS bragging points while keeping what’s intrinsically good about the Windows UI. 8)
