Aged and Distilled has released Napkin 1.1.1 with stability and cosmetic updates related to OS X 10.9 Mavericks (see “Napkin Offers a Fresh Take on Visual Communication,” 16 February 2013). The image annotation and diagramming app fixes crashes related to opening documents with multiple imported images, dismissing the iCloud sharing dialog, and returning from redaction mode to a canvas with an arrow item. It also fixes a problem where an image item would draw the wrong content and bugs that inappropriately displayed an inverted canvas. ($39.99 new from the Mac App Store, free update, 8.8 MB, release notes)
Sleep (and Lock) Your Screen
When you are walking away from your computer, it's fairly common practice to start your screen saver and lock your screen. But did you know that there is a built-in keyboard shortcut in Mac OS X to sleep the screen?
Press Control-Shift-Eject and your monitor sleeps without engaging the screen saver.
