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)
Close Word Comments Easily
If you don't like how precisely you must mouse in Microsoft Word 2008 to delete comment balloons, note that you can Control-click (right-click) a balloon to pop up a contextual menu. From the menu choose Delete Comment, and you're done.
Also, to get rid of all comments at once, choose Tools > Customize Keyboard and set up a keyboard shortcut to go with the DeleteAllComments command, available in the Tools category. Oddly, there's no Delete Comment keyboard customization option that I can find.
