We don't have the task stamp in the UI anymore but I am not exactly  
sure what happens under the covers. I assume if you import VJOURNAL  
items they just become unstarred items. If we import VTODOs are they  
starred, non-starred?

Unless there is a reason to export as VJOURNAL ie: to use with some  
other app, it doesn't seem worth supporting, particularly if we aren't  
differentiating between notes and tasks in the UI.  I think we export  
starred and non-starred non-event items as VTODOs so you would have to  
explicitly choose to export them all as VJOURNAL right? I guess this  
is an option.

Jeffrey, do you know any apps that use VJOURNAL?
