Google Notifier (Mac) - for multiple Gmail accts

Great tip at macosxhints - props to MELON here.
Basically:

• install Google Notifier for MAC
• duplicate it once its installed
• edit the Info.plist for the new copy of Google notifier
• change CFBundleIdentifier
• save your name and dets then quit.

You might want to change the icons for the different mail accounts - Patrick Joyce has described how, modifying the png icons for the particular instance of the app as duplicated above.

Now - lets say you have done this - but you also want to be able to just check a certain Gmail 'Label' - for example this might be 'important' email - a label that is updated by a Gmail filter for important mail.

If you were to do this, then the command:

defaults write com.google.GmailNotifierWORD Label -string "nameoflabelhere"
(note that WORD here is whatever you modified the Info.plist entry to be)
