Lemkesoft has released GraphicConverter 9.3 with several newly added features. The venerable graphic conversion and editing utility now has support for recording mouse clicks, exporting keyword palette entries as a text file, applying a browser extension filter to folders, and exporting a lossy PNG file. Other additions include the Lens Correction, Gradient Intensity, and Edges effects. GraphicConverter 9.3 also improves the speed of the browser, adds alpha channel support to multicrop, improves the Save for Web dialog, ensures the browser info pane remembers the last selected tab, and fixes several instances of possible crashes. Note that the Mac App Store edition is still stuck on version 9.2.1 as of this writing. ($39.95 new, free update, 239 MB, release notes, 10.7+)
Go Back and Forth Fast in Preview
If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.
The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).
