Pixelmator has been updated to version 3.0 with a new official name: Pixelmator 3.0 FX (though the Mac App Store, the sole place to purchase Pixelmator, doesn’t append the “FX” to the image editing and manipulation app’s name). The new release uses a new image editing engine that should improve performance dramatically, and adds non-destructive Layer Styles (such as shadows, gradients, and outlines), a Liquify Tool for warping images, and support for OS X 10.9 Mavericks (including App Nap, Compressed Memory, and tags). But these new features come at a cost, with Pixelmator 3.0 FX now selling for $29.99, rising from the special half-price “introductory” cost of $14.99 that it has been selling for since October 2012. ($29.99 new, free update, 35.9 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.
