Ubuntu One single file sharing

Hmmm. How do I change this to a 'wishlist' item?

There should also be a way to change permissions from read only to full read-write and back without having to re-share the file or folder. Right now, if I initially share my folder read only and then decide later that the person I am sharing with requires write permissions, I have no other option that re-sharing the folder that has already been shared. This triggers the whole share acceptance procedure that confuses both parties.

Now, when a person who is not yet registered with Ubuntu One accepts the share by following the link provided in email, and then I check the status of my share (not possible in nautilus!), the share tab on Ubuntu One web site will not show me email address the folder is shared to but instead something like https://login.launchpad.net/+id/Tp7J8Eh

Again, when a person signs up for Ubuntu One service there should be a language preference box, so that web interface and emails are in the language one can understand.

Email invitations to accept share should be sent out in system defined language (when sharing from Nautilus) and in language set as preferred in user profile when using web service. This will make Ubuntu One as accessible as Ubuntu itself.

Totally support this.

Especially when sharing settings, there might be single files that can be shared safely and others that would break the program if shared, all in the same directory. Example case: the bookmarks of a browser [you don't really want to share the cache or the history, just the bookmarks...].
