The Omni Group has released Export to iCal 1.0, a tool for exporting OmniOutliner tasks to the To Do item list of Apple’s iCal calendaring application. If an outline also contains columns for due dates and priorities, that information will be transferred to iCal as well.
OmniOutliner is a Cocoa-native application that enables you to track multiple to-do lists, with optional checkboxes so you can track your progress. (Cocoa is Apple’s object-oriented development environment.) Version 2.1 was released on Sept. 10.
OmniOutliner is available both in a limited free version and a licensed version that costs US$30.
