Useful Fruit Software has released Pear Note 3.1 with full support for Retina displays on Macs. The multimedia note-taking app adds support for using images (like photos of slides in a lecture!) in the just-updated Pear Note for iOS 2.1, and it now saves documents in an updated format that can be read by the iOS app. For older Pear Note documents that include images, Useful Fruit suggests opening and re-saving them so they work properly with the iOS app. The release also fixes a bug with saving that caused slides to move back, an issue where shared documents with special characters displayed improperly when hosted on Dropbox, and bugs associated with Spotlight results and the Quick Look generator. Finally, the Mac App Store version is now sandboxed. ($39.99 new, free update, 4.6 MB, release notes)
View Extra Audio Details in Snow Leopard
In Snow Leopard, Option-clicking the Volume icon in the menu bar displays a list of sound input and output devices. Choose one to switch to it; it's much easier than using the Sound preference pane. Also, hold Shift and click the icon to set the system volume, which is separate from the general output volume.
