My most disliked thing in Leopard
One thing I have read ,and totally agree with, is the statement that an operating system should not get in the way of getting your work done. As much as possible, it should be invisible. One of the best way for an OS to not get in your way, is to leave a path back to previous version interface elements, especially interface elements that a user knows well and that aids productivity. One of the best things about Windows XP is that no matter how much they tweaked the interface they left a path back to "Classic Windows" the interface that harks back to Windows 2000 (Win2K) and before. This Win2K interface , though not glitzy, allows users to get a lot of work done fast. It was a good workflow many of us old farts had established.
One of the best things about that Win2K Windows interface was the start menu. Clicking on start, in that interface, gives you a textual tree of your applications. This lets you arrange and get through and to your applications quickly. In Mac OS X 10.4 (Tiger, and before) you could drag your applications folder to the Dock, click on it, and get a similar interface in Mac OS. It was almost like having a start menu right in the dock. Well, that is gone with Leopard. In 10.5 Leopard if you put you Applications folder in the Dock and click on it you get the ugly fan. If you right click on it it becomes very apparent, short of some yet unknown terminal hack, you cannot get back to Classic Mac OS X behavior. When I want to use my very productive, tried and true Classic Mac OS X workflow I cannot anymore. That is just plain wrong! Apple could learn from Microsoft on this one.
