Noodlesoft released Hazel 3.0.14 to enable you to edit notification options from the file cleanup utility when running in OS X 10.8 Mountain Lion. Accessed via the gear pull-down, you can select Notification Center or Growl (if you have the latter installed) and specify which kinds of notifications should be displayed. (By default, Notification Center gets the nod if both are available.) The update also fixes instances of Hazel not keeping track of Trash if it is empty on startup and more reliably matches patterns with accented characters. Noodlesoft subsequently issued version 3.0.15 to fix a crash in notification options and a disabling of the gear pull-down when notification options are available but no folders are present. ($25 new, free update, 6.2 MB, release notes)
Shorten URLs in TextExpander
If your Twitter client doesn't automatically shorten URLs for you, you can use TextExpander to shrink those long links to tweetable lengths. First, add the Internet Productivity group by choosing File > Add Predefined Group > Internet Productivity Snippets. Then, to shorten a URL using a service like TinyURL, copy the destination URL to the clipboard, and type the abbreviation
/tinyurl to insert the shortened URL at the insertion point.
