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)
Single Time Machine Backups
Tired of Time Machine running all the time? You can turn it off in the Time Machine preference pane, but still initiate a single backup by choosing Back Up Now from Time Machine's menu bar icon. Of course, your backup is much less likely to be up to date, but Time Machine won't be taking any resources while you're trying to work.
