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)
Fun Way to Send Attachments in Mail
If you're working in a file that you want to attach to a message in Apple Mail, you can transfer the file to Mail easily: From the title bar of the file's window, drag the little proxy icon to Mail's icon on the Dock. Your Mac will make Mail the active application and open a new outgoing message, with the file attached.
(If your icon won't drag, the file probably isn't saved.)
