Create Finder Window with a Shortcut

While this doesn't solve your problem with the dock, using a keyboard shortcut can be much faster and can help in your workflow.

1. Activate Finder by clicking the desktop background
   (If the desktop is cluttered with windows, pinch out to clean it up and then click)

2. Use the New Finder Window shortcut: ⌘ + N

Disable Spaces Auto-Switching

On a side note, this does not effect the Finder if you have the Assign to all Desktops option selected. Link Here

This looks like a bug. I've tried rewriting the script various ways but the change only seems to take effect for new windows.

So here is a horribly hacky way to get this to work.

tell application "Finder"
    tell list view options of window 1
        tell column kind column
            if sort direction is normal then
                set sort direction to reversed
            else
                set sort direction to normal
            end if
        end tell
        set sort column to kind column
    end tell
    set currentPosition to position of window 1
    set currentTarget to target of window 1
    make new Finder window to currentTarget
    set position of window 1 to currentPosition
    close window 2
end tell
