; AutoHotkey script by wandersick (at gmail) 8-Feb-2011 [Revised on 7-Apr]
;
; goals
; 1. ctrl+alt+n to launch scratchpad
; 2. automatically always on top (like panels in ChromeOS)
; 3. alt+shift+t to toggle always on top status in any window
;
; supports:
; - Windows from XP to 7 (by junction)
; - enterprise and regular installation of Chrome
; - multiple instances but the latter run instances will only
;   be set to always-on-top when the currently active
;   (topmost) window is not a last instance of scratchpad
;
; before this will work, ensure appropiate version of Chrome
; and Scratchpad are installed and account sync is enabled.
