Regarding Single Application Mode

Regarding TidBITS’s “Hidden Single-Application Mode”:

But it goes further. Lurking in the scary bowels of Mac OS X for all
these years has been this little command, which brings back
single-application mode. (Go ahead and try it – it’s easily reversed.)
defaults write com.apple.dock single-app -bool true For
single-application mode to take effect, you have to relaunch the Dock
with this second command. killall Dock

Previously I use multiXFinder for this kind of job, which is free and play nicely with Snow Leopard. Additionally, it can also active the “Single Application Mode” while using Command + tab to switch applications. No need to mention the love of whitelist for some particular applications. Days ago I re-invited DragThing to my system and remember that DragThing itself has the exactly same feature.

Finally I use AppleScript to toggle this behavior, and it is lunched by FastScript.

tell application "DragThing"
    if not (hide other applications when switching) then
        set hide other applications when switching to true
    else
        set hide other applications when switching to false
    end if
end tell
