One of my favorite apps, Pixelmator, was updated recently adding a ton of improvements, bug fixes and a new feature called Brushes Collections. According to the notes that comes with the update, Pixelmator made over 20 improvements to this release. Included in the “improved” segment is the ability to change the background color of the work area by right-clicking on an area outside the canvas and choosing white, grey, or black; Automator actions are now compatible with Snow Leopard; Pixelmator now works properly as an external editor for iPhoto; and Clipboard content is now pasted into the center of the viewable canvas area.

There are a dozen bug fixes in this release as well, including a bug that sometimes caused ruler measurements to show incorrectly; borderless printing has been fixed; and a crash that could happen when closing documents has been addressed.

Pixelmator 1.5.1 is a free update for registered users. For new users the app costs $59.
