I've been running 12.01 since it came out, and I also was happy to see a few minor annoyances disappear with the update.
While we're on the subject of wish-lists,
other than lack of pgp support (which I know there's no point mentioning from our previous discussions), these are the two main things I miss not having:
The ability to word-wrap/re-flow text as one types (but I'd settle for: in response to a hot-key) in the mail client's plain text editor rather than have to save-as-draft and then reload the draft message in order to see the effects of word-wrapping, would be very welcome.
Being able to associate additional email addresses with a single 'contact' would also be a nice improvement.
Also, any way to turn off those crash logs that get dumped into /var/tmp/ when one forgets to exit Opera before logging out of X?
