The Growl Project has released Growl 2.0, a major update for the system-wide notification utility that brings compatibility with Notification Center in OS X 10.8 Mountain Lion. With this new release, you can set Growl to route all of its notifications through Notification Center (rather than use Growl’s standalone pop-up notifications). However, you’ll still find some apps (including Dropbox) using Growl’s notification system instead of forwarding to Notification Center due to the requirement that developers update their apps to the Growl 2.0 API. The update also adds support for Prowl and Boxcar, two utilities that enable you to receive notifications from your Mac on your iOS device. It also reportedly resolves the high CPU spikes and multiple crashes suffered by the previous version. ($3.99 new from the Mac App Store, free upgrade from previous Mac App Store versions, 6.1 MB)
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.
