Look - if you don't like the Dock, don't use it. You can achieve almost complete OS 9 features with ASM (or the new MenuStrip 2.0) for appilcation switching. If you want your Window Shade features back, get the new Window Shade system preference. Then, just set the Dock to hide. Check version tracker for URLs to download from....
If you are having trouble with Dock clutter, try this...
Remove ALL your applications from the Dock. Create a new folder in your home directory. Drag aliases from all your applications to this folder. Call it whatever you like (I called mine "launch"). Drag this app to the dock. When you want to launch an app, click on this folder. You have the EXACT same functionality that you had in the OS 9 equivelent of adding aliases to your Apple menu. Plus, you can add a custom Icon to this alias folder which will show up in the dock. This way, all your Dock items that you want to launch will be located in the folder, and all the actual items in the dock will be launched applications, of which you can get about 15-20 before your dock starts getting smaller. Are any of you really keeping more than 20 applications running at once? I don't think so....
I think the Dock could use some tweaking, but overall it works. My main beef with it is that since it's either centered or pinned right or left, the Icons are always shifting around, making it hard to create motor memory of where your items are. I'd like to see the Dock have the option of taking up the entire bottom of the screen, with the Finder Icon aways pinned left and the Trash always pinned right. So when more icons get added to the dock, before scaling of the Icon starts, first the space between the Icons will get smaller, then the Icons will start scaling. Some people might like their Icons to be flushed left (again with finder locked on the left and trash locked on the right), and as icons are added they take their spot to the right of the last Icon.
These suggestions aren't monumental. The dock as is works fine for an application switcher and repository for drives, documents, etc. Give it a fair shake and you'll grow to appreciate it.
