Got it!
Bad news first: the format is not that easy to handle. Dunno what happens if modified and restored to mede8er. I guess it contains some binary code, but also…
Good news: there is something resembling your favorite, in plain XML style, but I think that they really are your "Network Shortcut" shares and not your favorites…
You may try, at your own risk, to edit the section between <Storage> and </Storage>, changing the content of the tag <Timestamp> for each item: Timestamp is a numeric value representing the date and time the share (or favorite) was added to the system and it used to ORDER the items. Just change the last digits on the the right so the progression reflects the order that you want.
Backup your cfg first then cross your fingers and… use Text Edit to open the file, then search for "<Storage" (senza virgolette!).
Good luck!
PS SI.
PPS Si, infatti.
