[Design] Alpha 2 background synching

[Sheila Mooney]

I have put together a spec for alpha 2 background sync.

http://svn.osafoundation.org/docs/trunk/docs/specs/rel0_7/ 
Sharing-0.7.html

Mimi, Morgen and I have been discussing the following issues offlist  
and thought it was appropriate to send to the design list...

1) Should import/export be background tasks as well - should the user  
be able to work on other things while these operations are taking  
place? I would probably make sense to have this running in the  
background as well given that we want to unify the experience for  
getting data in/out of Chandler.

2) What happens when the user clicks Sync All. Do they get the modal  
dialog - probably not. It makes sense for this to simply force a  
background sync. Basically this means there would be no more Modal- 
Lock-Me-Out-of-Chandler sync. We would have no dialog popup when the  
sync finishes either.

3) If a background sync is running and the user clicks "sync all"  
what happens? The current sync will quit and start again. Does the  
user need any feedback in this situation?

4) Since we are eliminating the popup dialogs, how does the user stop  
a background sync? We probably need to have a stop sync button,  
either on the toolbar or could be a menu item.

5) Is it possible to have a link in the status bar so when the sync  
finishes, we could put a message in the status bar then link to a log  
file or something like that? We have no idea if it's difficult to  
stick buttons/links in the status bar.
