Cultured Code has released Things 2.1, an update to its task management app with improved integration for OS X reminders, providing more control over which types of reminders are displayed. The maintenance release also fixes an issue where interacting with an item in the Daily Review list could cause keyboard shortcuts to stop working, resolves a problem where dragging a Today item assigned to a project to the top of the Today list would remove the project association, includes items from repeating projects in search results, and returns links to Entourage 2008 email messages to displaying the email subject (as previously handled in Things 1.5 for the Mac). ($49.99 new from Cultured Code and the Mac App Store, free update, 17.2 MB, release notes)
Option-click to Hide Apps Quickly
This trick has been available in the Mac OS for years, but many people still don't know it. If you have too many windows cluttering up your screen, you can hide specific ones easily as you work. When you're in any application, hold down the Option key and click on another app's window, on the Dock, or in the Finder to switch to that other app and simultaneously hide all the windows in the previously current app.
