application-switcherfinderwindow-manager
Let's say I have all my Finder windows closed. I'm in an application, like let's say Google Chrome. I ⌘–tab to the Finder icon to switch to Finder. But it shows me nothing… no windows, because I have no windows open. I have to then invoke ⌘–N to open a Finder window.
Is there a way to get OSX to automatically open a Finder window when I ⌘–tab to the Finder icon to switch to Finder, since anytime I switch to Finder, I always want a window?
You can try using the AppleScript found on this page.
I just tried it out and it perfectly works fine in Chrome 12.0.742.122.
It's extremely easy to set up:
OpenUrlInNewChromeWindow
You have several different options:
While this doesn't solve your problem with the dock, using a keyboard shortcut can be much faster and can help in your workflow.
Activate Finder by clicking the desktop background
(If the desktop is cluttered with windows, pinch out to clean it up and then click)
Use the New Finder Window shortcut: ⌘ + N
Uncheck the Missions Control preferences checkbox to switch to a space with open windows for an application:
On a side note, this does not effect the Finder if you have the Assign to all Desktops option selected. Link Here

COMMAND-TAB and hold down COMMAND.
Release TAB, keep holding down COMMAND,
then press OPTION and hold it down.
While still holding down OPTION, release COMMAND. Then release OPTION.
As far as doing it automatically you'd probably have to script something.
