snarke -- cool, but it only seems to return the collected tasks; looks like it doesn't go beyond

return collectedTaskInfo

-- in Script Editor, it produces a result list, no iCal change occurs.

Also, when running the installer, no icon was added to the toolbar, had to Customize Toolbar manually... And it does nothing from there as well.

Upd.: commenting out the above return line did the trick.

OmniBrian: there's a pending Sync Flagged to iCal feature request, can you please add all posters to this thread and the download count to the votes? :)

Also -- Things do exactly this with Today instead of Flagged. However, when you un-Today in Things, the Todo immediately disappears from iCal, and toggling Today star back on makes it reappear back (try it). Yet here, unflagging a task leaves it hanging in iCal...

Checking the iCal-synced task in Things makes it complete in iCal and vice versa, here if you check a todo complete in iCal, it still shows not complete in OF.

That's why we need it as a deeply managed feature, to keep track of it by flagging/unflagging event (try that in AppleScript).

A fun way to see this is to run Anxiety with the iCal calendar you sync to, and check-uncheck, today-untoday, flag-unflag tasks in OF or Things, and see the contents of the list and stati reflect the changes at once (Things) or not (OF with tasks to iCal script).
