Ok, will do. As for removing whole path - check. ;)

Hm, I think I use it in a number of locations now. I'll take a look at  
documentation of GLib to see if things are easily replaceable.

Sorry, my bad. Yes, we show dates of all backups.

Showing the whole file in place by default is probably unnecessary and  
"open" option is probably a valid solution (although to streamline the  
interface, showing at the very start current version and when older  
versions come in showing those (older) versions would be nice so that  
user would see how file changed over time). As for performance issues  
- since we would only retrieve a single file a number of times I don't  
think this should be a problem, especially if we use incremental  
loading and load older versions as data comes in.

Time machine basically shows you directory as it was on a certain date  
(a week ago, a month or two ago, etc.) and you can open file as it was  
on that date - there is no diff. Adding it could help user a lot since  
it would be much quicker for him to notice the changes that he made  
(and that's basically the rationale why we should implement it).

Hm, yes, I didn't think of that. It would probably be worth thinking  
how best to incorporate partial restore, file history and directory  
history... If I understand partial restore correctly, this  
functionality would basically be achieved by showing directories and  
offering to restore directory and all of its subdirectories and files  
(if user activates directory history at "high enough" level)?

Or did I miss something about partial restore?
