Comment 11 for bug 612988

Ok, several issues I need to expand a little on, here.
The current nautilus extension has no way of adding things to the nautilus toolbar, nor to the view menu; we're limited to emblems, property pages, context menu entries and sub-entries, and the ribbon.
The current ribbon uses up a lot less vertical space than when this bug was opened. It can be further collapsed, and the collapsed state is preserved. It can be disabled completely via the context menu (we need to find a way to have nautilus redisplay the window so the ribbon goes away instantly, but that's another issue).
The current ribbon only shows up in some folders: in folders that are already synchronizing, and in the toplevel "special" directories (Music, Videos, Documents, etc).
The current ribbon, and the extension as a whole, does not even start up if the user has disabled file syncing.
There is a bug, bug #613219, that the nautilus extension will start syncdaemon even if it is has been removed from the startup applications. We'll be fixing that one.
When the user clicks the checkbox with syncdaemon connected (the usual case), there is a short delay (less than a second as measured from this hotel's slow network in argentina) and then they can click the checkbox again and the sync is aborted. syncdaemon works for a little longer to cancel all the jobs it fired off, but the system remains responsive. There are corner cases such as folders with a huge (50k+) amount of files where the delay is longer; if syncdaemon is disconnected, the delay is longer while it connects and etc, but it definitely becomes responsive again as soon as it's connected and before the upload starts.
