Wah, wah, wah!
I am getting so tired of hearing this stuff about stacks. They are missing the ability to customise the icon on the top and the ability to navigate the stack. Big deal. It's already been implied that the functionality will likely be added back soon as well as the ability to use "smart stacks."
I agree with you about the appearance issues with Stacks. I disagree with you on the functionality issue. Under Tiger, I could get to any file on my hard disk in a single click and drag. Let's see how that works on Leopard:
1. Click on folder in dock
2. Click on the folder I want
3. Keep double clicking on folders until I see the file I want
4. Double click the file I want
5. Go back to the Finder
6. Close the folder which was left open
7. Go back to the application and start working
That's a HUGE increase in effort to do something that is as common as opening a file. I do that dozens of times a day - and Leopard's process stinks.
With all the other things that could be wrong about an Operating system.... The Stack issues are really Trivial & Cosmetic.
Not the loss of hierarchical menus. That's a major loss of functionality.
