The folks at Cultured Code have crossed releasing Things 1.4.5 off their to-do list. New to the task-management utility is support for the Things URI scheme, which was previously offered only in the Things iOS apps. The Task Modification Date is now available by AppleScript. Among the numerous bugs fixed are an issue where items could reorder themselves after syncing, an issue where marking items complete from within search results would bounce you to the Inbox, issues with grouping and sorting of tasks and projects, various issues with recurring tasks, and a crash under Mac OS X 10.4.

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.
