Stairways Software has released Keyboard Maestro 5.1, which brings a number of improvements and fixes to the automation utility. Most notably, the update adds a new For Each action that enables you to loop over a variety of collections (including files in a folder, mounted volumes, lines in a file, and more), acting on each item in turn. Other additions include a Percent Encode for URL filter and a signed developer ID that is used by OS X 10.8 Mountain Lion’s Gatekeeper security feature. The update also fixes a crash that could occur when a called text factory no longer exists, as well as a lockup when entering quoted strings in calculations. Read a complete rundown of all the improvements and fixes included in this update at the company’s blog. ($36 new, free update, $25 upgrade from versions previous to 5.0, 16.3 MB, release notes)
Compare More Easily in Apple Mail
In Apple Mail, if you need to work back and forth between two different views of Mail's mailbox contents, you can do so quite easily. For example, you might want to look at a mailbox holding all filtered-in sales orders from the past week while also looking at a smart mailbox showing unanswered customer questions.
To avoid constantly clicking between mailbox views and losing your context each time, choose File > New Viewer window to get a second window and then arrange each window as desired.
