Things, one of the leading task manager apps on Apple's OS X, has seen a long-awaited update to version 2.0 today. It brings to a close some five months of public beta testing of a new Cloud syncing feature — which distributes your to-do list across the full range of Apple devices, courtesy of updated iPhone and iPad apps as well. Also on the new features list are Retina display support for the new MacBook Pro, an entirely re-engineered core for "blazing fast Things Cloud performance," visual refinements that include a reduction in window chrome, and an all-new Daily Review section. You'll need to be running OS X 10.6.6 (Snow Leopard) or later to be able to apply this update, which is free for anyone who's already purchased the app.
